I am posting this as a note to reader's of the ICCA journal:

In the editorial section of ICCA the following paragraph appears,

"...the Indonesian program GUNDA-1 participated, and in
in the 16th Open Dutch Computer-Chess Championship
(Leiden, 1996) the program RAJAH was entered. Both
programs were based on Hyatt's world-wide available code
of the program CRAFTY."

And there is more nonsense in the article about giving acknowledgement
to proper sources of programs. RAJAH is in no way based on CRAFTY. It
was written by me over the last few months as a hobby project.

I am not sure how such misinformation could have been published - one
wonders what other "truths" the ICCA journal has been publishing. It is
also more appalling that this article was written by an individual of
considerable stature in computer chess: Jaap van den Herik. One would
assume some one of his likeness would have learned to get his sources correct
over the years of publishing articles/research papers.

one learns to not expect *anything* nowadays. :) In any case, you and I
have chatted several times, my impression is that you have "done your own
thing" from scratch. No idea where this nonsense came from. You should
certainly write them and correct the misinformation of course, and chide
Jaap for writing something casually without checking information...

I think the ICCA would never come to the idea of misinforming people !
Ha Ha Ha !!

Jaap van den Herik ??
He is a person with a very very godd reputation. How can you attack
him here in this ugly way ?!

Please specify your problems. Jaap is a honorable man....

The only reason I post this in a public forum is that it was published in the
ICCA and a lot of programmers/aficanados of computer chess here read this
magazine. Maybe you have not read the article that was published by the ICCA
in its current issue. There is some discussion in the article about
GUNDA-1 and RAJAH being based on CRAFTY. No one from the ICCA or even
Japp van den Herik ever approached me and asked about my program. One then
wonders how they can publish this information.

Also I was quite angry about having my efforts on RAJAH diminished by the
article. A lot of hard work has gone into RAJAH and it is rather disheartening
to read such stuff.

I forwarded your original post to Tony Marsland. Someone else had spotted this
already and forwarded it to him before I did. They are contacting Jaap in order
to figure out what prompted him to write this stuff.

I haven't see what they wrote, since I haven't gotten my ICCAJ yet.

This will get straightened out, obviously.

Normally one should research or find out before one writes something.
But from my experience in several PRINT MEDIA over the years I can
tell you, that very very often people write without knowing anything.
Some are so beloved by their own writings, that for them the words are
more imortant, than the fact if the information in the article is true
or not.

No - I don't read the articles in this ICCA-journal. I only study the
nice pictures there, and the text below the photographs, e.g.

Edition Vol.19 No.4 , page 278,
Picture with Jaap van den Herik:
EASY WORK: A TOURNAMENT WITHOUT DISPUTES

These comic-like photo-stories are much better than Spiderman or
Dr.Strange....

Obviously ! Straighten it bruce. BRUCE FOR ICCA PRESIDENT.

Take Bruce as TD instead of Jaap. Pay him for doing it.
We talk about it in den haag, together with Jaap and bruce !
Ha - that will be a nice TALK.

I have an eletric-shocker against robbers, I will better take this

APOLOGY
=======

Mr. Valavan Manohararajah has informed me and also the readers of
rec.games.chess.computer that I published some misinformation on his
program RAJAH by stating that it was "based on Hyatt's world-wide
available code of the program CRAFTY" (ICCA Journal, Vol. 20, No. 1, p.
2).

The information came from reliable sources, which I would not like to
blame. I have not triple checked it with the author simply because I
used
the information to honour Bob Hyatt's contribution, and in no way to
belittle Mr. Valavan Manohararajah's program.

Neverthesless, I apologize for giving unintended misinformation on the
program RAJAH.

Jaap van den Herik
Editor of the ICCA Journal

triple checked? Verifying the sources' information would have been
checking. Verifying twice would have been double checking. Verifying
three times would have been triple checking. It seems to me Mr. van den
Herik didn't even bother to *check* his sources (assuming that he had
more than one).

Agreed. An apology that refuses to accept blame, and, worse, makes
disingenious (or, shall I say, fabricated?) excuses, is an empty apology.

It's bad enough that Mr. van der Herik unintentionally libelled Mr.
Manohararajah. This un-apology simply adds insult to that injury.

Libeled is the wrong term. That implies telling something false with
the *intent* of causing that person some sort of harm, such as harm to
their character, name, reputation, etc. Nothing like that was done.
There was obviously *no* intent of any kind here... as the sentence
below this clearly points out....

I'm not going to defend what Jaap wrote in the ICCAJ, it was wrong.
But "libel" is an intentionally damaging act, so to unintentionally
libel someone makes no sense.

Just so everyone knows, here is the relevant part of what he said in
the ICCAJ:

"The question posed above theoretically has been partially answered in
recent practice. In the 14th WMCC [sic] (Jakarta, 1996), the
Indonesian program GUNDA-1 participated, and in the 16th Open Dutch

Computer-Chess Championship (Leiden, 1996) the program RAJAH was

entered. Both programs were based on Hyatt's world-wide available
code of the program CRAFTY. Since both teams gave due credit to
CRAFTY as their original source, it is comparable to using ideas from
articles while giving appropriate reference. Nevertheless, the
question remains to what extent can we prolong the similarity of
publications and programs. For articles, we do not allow plagiarism.
For algorithms and programs I believe we are in a state of flux.
Yet, the researcher who is the originator of the ideas whould always
be given pride of place."

I saw this thread before I got my copy of the ICCAJ. I was all ready
to read some angry tirade accusing Manohararajah of stealing. Instead
I find this, which is CLEARLY incorrect, but which at least doesn't go
that far. All he did was mis-attribute a program, he didn't accuse
Manohararajah of any unethical act.

If this had happened to me, I would have been upset. I would
have probably written something to the ICCA, and I would probably have
also made some comment here in the newsgroup, like Manohararajah did.

Rajah is clearly an original program, not derivative.

But any comment to the affect that Jaap has "accused" or "damaged"
Manohararajah is too much. It was a mistake he shouldn't have made,
but some of the negative comments you will read here in this thread
are quite similar to the reaction you get from the crowd at a baseball
game after a questionable call against the home team -- sustained
extreme negative reaction after the umpire does ANYTHING for the rest
of the game, no matter whether the call is good, bad, or unclear.

Now that I have said some stuff that will get me flamed by the usual
people, I would like to say some more stuff, the substance of which
they may ignore.

I oppose the entry of source-code derivative programs in ICCA events.
Gunda was a weird case because it was produced by the host country,
as its only entry, and because there had been miscommunication between
Bob, the folks doing Gunda, and the ICCA. In this case you grit your
teeth, frown, shake your head, and say "yes". In other cases, I would
argue that if someone wants to enter a program in an ICCA tournament,
they should write it.

For this reason, I would also be opposed to another point Jaap made in
his editorial. He mentions the case of Nimzo, which can have its
positional weights tweaked by the user. Donninger is on record as
saying he wouldn't oppose entry of a tweaked Nimzo into a tournament.
I would like to say that I oppose this, there is a lot more to a
program than positional weights.

It is another oversight/logical error/ (un?)intended shift of arguments and so
on of our most prominent and loved computer freak Bob Hyatt.

Bob's thinking (?) as lifetime defendent of ICCA officers is absolutely and
100% wrong.

Maybe it's sort of *cultural* (mclanr) fall out -- I don't know.


Proof:

Valavan quoted in his first article the following from ICCAJ:

"...the Indonesian program GUNDA-1 participated, and in


in the 16th Open Dutch Computer-Chess Championship
(Leiden, 1996) the program RAJAH was entered. Both
programs were based on Hyatt's world-wide available code
of the program CRAFTY."

Now let's take a closer look.

In some way RAJAH was compared with GUNDA-1, alright?
They were both based on ...

If I remember right, GUNDA-1 was almost a 99% identical clone of Crafty. So
identical that Bob -- in the time back in last autoumn -- didn't know exactly
which were the differences ...
Maybe some different book tuning .. I don't know.

Now, if you take this for granted, RAJAH remains as a prg that was NOT created
by a programmer on his own but copied, prepared and renamed. (I personally
don't know nothing about RAJAH.)

It is right, that neither the cloning of GUNDA-1 nor *that* of RAJAH -- if it
were true -- would have been wrong in itself. Bob made clear a lot of times
that he had nothing against it apart from some unintentional bad side effects
when taking part in the same tournament. Remember that GUNDA once looked
*better* than Crafty himself. :)
I'd like to add that I thought the participation of a Crafty clone under the
flag of the hosting country really a very good idea. Not joking.

Being compared and falsely compared with this clone the REPUTATION of Valavan
Manohararajah was not at all *belittled* (Jaaap) or *harmed* (Bob)? With or
without a friendly *Mr.* in front of his name?

Intended or whatelse -- all this stinks/tastes/smells of an *allowed*-thought
superfluous, elitarian, western, colonial, and what more degradation of the
creative work of a *not so important* (?) and *not so well-known* (?)
programmer collegue *from down under*.

BTW, Bob, this *the information to honour Bob Hyatt's contribution* sounds like
a tricky/cooked/sought manipulation, no? You don't need that. What the hell did
you learn from your kids coming from all parts of the world? I mean ...
Logic is world wide the same. The habits are different. We shouldn't act
without necessity as tricky Dicks. :)

I took it at face value. Many people seem much more excited about my
releasing the source to crafty than I am myself. I don't see this as
any big deal. I thought awarding me the Novag award for doing this didn't

releasing it. None of that is the *reason* I did it. It was a personal

release the source will be a personal decision.

I'm waiting for your 100% wrong proof however... nothing you've said
contradicts my definition of "libel" which comes from Webster's...
There has to be intent. I don't see any intent to harm anyone. I
see intent to "pat Bob on the back" which was not needed, but I don't
see any intent to defame the reputation of another chess programmer.
I consider him a friend of sorts, even though we've never met, because
we converse all the time electronically.

Why does every little faux pas made by an ICCA person result in red
flags, air raid warnings and scud missles? I make many mistakes. You
made one in misattributing something about CSTal's Nxf2 being unsound,
which I didn't say. And it's no big deal to keep rehashing over, and over,
and over, and over....

How exactly do you come up with this bullshit? He didn't liken it to

Not according to my dictionary. Libel is defined in part as
"a written or oral defamatory statement or representation that conveys
an unjustly unfavorable impression". I don't believe intent enters
into it. What authority do you and Hyatt have for your claim to the
contrary?
As for derivative programs I do not think a blanket ban makes
sense. Suppose A and B write a program together and then split up each
producing individual programs based on their joint program. Which
would you allow? What about programs like gnuchess which have been
modified by many people?
However I do think it is reasonable for tournaments to reject
entries without significant original content.

It comes from US court decisions about libel and slander. Doesn't have to
be false, in fact. A true statement can still lead to a slander judgement

I don't know if anyone else responded (on your behalf or otherwise) to
that call for nominations for this award, but I did.

I nominated you for this award because I figured Crafty had helped a lot
of people, and that you deserved recognition for this. Also, I figured
that if I didn't do this, someone would get the award for writing some
paper on some arcane sub-variant of conspiracy-number search or
something.

It's not just that people can see a high-quality chess engine, learn how
it works, and improve their own, I think that the existence of Crafty may
also spur other research, since people have something they can perform
various experiments with. This thing you are doing with Newborn,
involving searching that test suite out to 14 plies, is an example.

I also mentioned your contribution via this newsgroup and via the chats
on channel 64 on ICC. All nonsense involving politics and the ICCA and
bazookas, etc., it's obvious that you are helping a lot of people by
talking.

I know lots of people who've gotten further than they otherwise would
have had you not done this stuff. Myself included, obviously.

Upon reflection, my comment about mis-attributing a program is wrong.
There is more to it than this. If he had said, "person X wrote this",
when in fact person Y did, that would be mis-attribution. But this is
brought up in the context of whether or not to allow derivative entries,
which is not the same thing.

In the former case, someone else gets credit for your program. In the
latter case, you get credit for having not written your program, which is
worse.

So, Fong's point is taken, to that extent.

I am not in favor of admiting derivative entries in computer chess
tournaments, as it would be very difficult to assess the degree to which
the entry was original. Case in point: Gunda. Nobody knows what they
did to Crafty, if anything, to create that. So we may have had a
double-entry.

Personally I would view any derivative entry with disfavor, since I would
question the degree to which the original program was tweaked. The

It is absolutely *not* the case that libel has to be intentional. It simply
has to be damaging. Since this issue of 'intentionality' is being used, in
several replies, as part of your defence of the ICCAJ - you should take
more care to use the language correctly.

It is probably a moral defense to making a damaging statement about
somebody to say that it was not intentional, but it is certainaly not a
legal defense.

This is true, but its a (endlessly typical Hyattian) sidestep from the
original.

Legal status:

1. Any untrue written statement which is damaging is a libel, intentional
or not.

2. A true written statement, published with the intention to defame, can
also be a libel. This is more legally contentious since the defense of
'fair comment' then arises. It is quite difficult, but not impossible, to
get libel damages out of a court for a 'true statement' libel.

However, the argument is not about case 2. ( as Bob is trying to switch
towards), but case 1. - an allegedly untrue written statement.

Additionally considered is the level of damage. Normally libel actions get
reserved for serious defamation (financial, sexual etc.). If RAJAH is a
'fun' program, the author a student, no intention to ever publish, nor use
the program for research or career development; then there is probably not
much damage, and hence libel is too big a word.

If the author has career development plans within computer chess, then the
ICCAJ statement is damaging, and can never be fully repaired. The offending
issues of the ICCAJ will always be in circulation, future readers may well
spot the original article and not any correction and so on. An unscrupulous
competitor might use the article to undermine a deal being made for this
program.

I agree. But how could this be enforced?

Maybe for future computer chess tournaments competitors should sign a
declaration that the program they are entering is their own, and
contains code they have written. This could be taken further so that
some programs, chosen at random, would have to show their source code to
the TD.. A bit like dope testing in other sports?!

I for one wouldn't want to enter my little chess program into a
tournament where the competitors are crafty clones and nimzo tweaks. And
not just because the crafty clones and Nimzo tweaks would be rather
strong ;-) Half the fun of these tournaments is discussing programming
ideas with the opposition during the game, and what would the operator
of a crafty clone have to say?

Didn't a little birdy mutter some time ago on this newsgroup that two of
the German programs playing in Jakarta were in fact the same program? I
don't like this, and would like to see steps taken to avoid this kind of
thing happening in the future.

However, on the flip side, mistakes happen all the time in top-quality
journals, in books, in news stories and articles and so forth. And in
the US, the courts have generally found that it takes "intent" to win a
judgement. An alternative defense has also been "neglect" as in hearing
or reading something in this newsgroup, and then making that into a 6pm
news story on TV without carefully checking details. In the case of
Rajah, this last certainly happened. The intent part did not. At least
here, our juris system is not intended to punish technical mistakes that
did not cause other than incidental harm, and which were made in a casual
and unintentional way. I'd suspect that if I had been at a computer chess
event, and heard a couple of people say that Rajah was based on Crafty, or
was based on gnuchess, or was based on ... that I would likely remember
that, and I might mention it without thinking, when writing about the
authors of gnuchess, or myself for example, because the topic was not
Rajah at all... it was Crafty. As to the 500 copies of the ICCA journal
causing lasting damage, I don't buy it. Otherwise scientific journals
would be hopelessly bound up in the legal system, because they print
corrections, retractions, modifications, and so forth all the time since
they are printing things that are "leading edge"...

However, back to the main point. The author of Rajah has already accepted
Jaap's appology, and has said he intends to write a small blurb for the next
ICCA journal. If it's good enough for him, why's everyone else jumping into
the frey. It's almost difficult to decide who thinks they were harmed by
this. In fact, it looks like the typical "aha, here's another ICCA mistake,
let's keep fanning the flames so that it doesn't go out..." Under *your*
system, I get run over by a car, and settle with the person that did it, yet
you continue to keep this "in the news." Who should *really* be the ones to
settle this? Jaap and Rajah's author? Or you and the rest of the anti-ICCA
gang? It seems like the latter, from reading here...

: Tom King

I've always been "anti-clone".. Gunda was originally going to be *the*
Crafty playing there. But lack of communication convinced me that I had
better enter Crafty or else would not see it play at all. I did. They
entered at the last minute. It was a problem. We both finished in 4th
place I believe or 4th-5th tied, or whatever. And it was not particularly
fair to others playing there, regardless of whether you consider Crafty a
strong or weak program. If you enter 4 duplicate weak programs, chances
are pretty good that one will do pretty well.

I have no idea how to enforce this. If we aren't careful, there can be *no*
new programs, because all of the neat recursive alpha/beta variants have been
used, and published already. So you can't do a new search. You can add an
extension here or there, but is that "new"?? Hard to see. Evaluation is the
same thing. Cray Blitz was the first program with square of the king code for
passed pawns. This was working in 1974. Does that mean no one else can use
that idea? Ken Thompson was the first I remember that used the recapture
extension... Slate/Atkin introduced iterated search, Greenblatt introduced
transposition tables (hashing).

The problem is, then, how to figure this out, and I don't see a way. I could
look at most anyone's source and tell whether the basic idea came from Crafty,
because there are few bitmap programs, and even fewer using rotated bitmaps.
So far as I know, rotated bitmaps to compute the attack vectors was something
that was discovered by me as I worked on the original bitmap version of Crafty.
I reported it here and at least one other program took the idea and implemented
it before I did.

Hopefully you see the problem with detecting "clones" since if you were to take
the "union" of all chess programs, you get a substantial part of all of them
already. It's the {myprogram} - union({myprogram},{yourprogram}) that is the
interesting part. What have you added? One line? or 10,000 lines?

It's a difficult, if not impossible, thing to work out. It's hard enough to
catch students copying code when the programs are only 500 lines long. In a
30,000 line + chess program, it might be impossible without spending a *lot* of
time wading through everyone's source...

You didn't see the private email, but Jaap also invited the author of
Rajah (note I don't post his name here because I don't want to butcher
the spelling.. :) ) to submit a short article on Rajah, which he promised
to publish along with Jaap's appology. I think this was the best that could
be done, other than to never have made the mistake in the first place. I
think Jaap's done a great job in the JICCA. One small mistake doesn't wipe
out all the good he's done. A small wart on a spotless run as editor for
many years is *not* a big deal. If every issue had similar mistakes, it
would be different. So far we've seen two flame wars here, one about the
Botvinnik article, which might should have been reviewed better before it was
published (but with Botvinnik's reputation, it would be unlikely that someone
would have challenged him) and now this.

I have a huge stack of these things in my office. That's a low percentage...

Pardon me, but if you had to enter your article in full content into your
footnote, wouldn't it damage your reputation as honoroble/creative/interesting
author?

Let's not play dirty. We all know that GUNDA wasn't a *big* invention, no?
Although it was allowed. But going on world tourney wouldn't be appreciated,
no? And that is the point. The author of RANJA was hurt in his reputation NOT
because he might have done something scandalously forbidden but something that
could be laughed at. And there are people outside the sphere of ICCA officers
who certainly do care about not losing their *face* in public. World wide
acting officers of ICCA should be able of taking care of this fundamental fact.
Period.

As already stated, behind three walls of chuckles there certainly was an

Correct, not a big deal compared with the cases of hundreds of misused children
by real professors, but we shouldn't forget about those principles well known
in science in our good old western world ...

Just to put the definitions right.

For a possible damage of one's reputation there's no need of *intent* or
whatever included.

But in this case *I* see a clear intent. A political intent by an ICCA officer
to change something that might have become apparent with Gunda last year. Now
the Rajah incident at Leiden was shown as sort of increase of a wrong
development. Although not forbidden yet this *should* be banned likewise
plagiarism is already treated in scientific articles.

But the damaging attack lay also in another context.

To make this a bit clearer let's presume a well known author of computer chess
like Moreland or Hyatt would have been put in the tradition of Gunda which was
a 99% clone of Crafty ...

For me the scandal lay in the fact that in this case the ICCA officer surely
would have checked the details with the persons mentioned.
But in case of the indian author that same precision wasn't important.

What Herink tried to belittle with his forgotten triple checking was in fact
the main thing to do. Only that it had to be the first instead of the third
check. In case of other names it would have been.


And finally. To all the defenders of the ICCA staff. There's no justification
to point at *scud missile actions*. This is another slap into the face of
someone who *was* and *felt* hurt and damaged. There's no need to hurry by in
cowboy attitude and to yell *but that was not at all damaging anyone*. Did
these people ever think of this: if some people at Leiden were convinced that
Rajah was simply a crafty clone, that might have given some eye blinks, head
shrinks, open laughter down the hall behind the back of Rajah's author, no??
All this which ended up into a typical sophisticated article in a scientifical
journal could be simply effacicated by a 30% apology which repeated sort of
arrogance ...?

All these reactions seem to be lacking smartness to understand different
attitudes worldwide, instinct for decency and the right words at the right
place ...

Surely the responsible officer who started this mess should take his hat.
That's common praxis -- worldwide. But to even suppose that ICCA officers could
loose their publical image seems out of the realm of imagination of some of our
usenet friends.

But don't blame me, I'm only the reporter.

I would like to point at the may be ironical content of putting together these

And I even go further. For me it was clearly an intended changing of politics
where Ranjah and his *author* (in the ironical sense of the ICCAJ author) was
just an example of increase agter the well known Gunda example.

How do you know?

Being compared with GUNDA. And not being in the hosting commitee of an Wch
event? Travelling around the world with my program which is a 99% clone of
Crafty? Wouldn't this be hurting my reputation as serious programmer?

>If this had happened to me, I would have been upset.

Yes, and you know why? Because the scandal is that someone -- no, an officer of
ICCA -- could make this assumption publicly without checking/asking you
personally, no? Can't you see that Herink's *mistake* came out of the damned
sure opinion that *this* *author* fitted the momentary political needs of the
publisher? In case of others programmer he surely would have checked a bit
closer.

But now it's too late. He did hurt the public image of a programmer for
days/weeks and months. And the reaction should be to retire this man from his
job in ICCA. Because with aplogizing (and in that *half* way) and an article
six months later it's not done.

Note:

If you're in official mission such errors which in effect did hurt someone
important should lead to retirement even if you personally are not guilty
because you relied too much on some information of your aids. Period.

Reading this again do you feel the same disgust I realize just now?
How one could explain to you that the way Valavan published his post he must

You needn't any mandat to say your opinion?

Bollocks, Bob. I'm merely correcting your (false) posting that libel has to
intent based.

I've posted hardly anything on this thread, you've posted the usual ten
million, who is fanning flames ? This is a duscussion medium, we can talk,
no ? If Rajah's author has allegedly accepted Japp's apology, that's fine
by me; in the same circumstances, I'ld have accepted it too - not much else
could have been done.

But please, let's stop this personal jibing, where anybody who says

I didn't understate the harm. You immensely overstated it. Last ICCA
shows about 500 paid subscriptions. Out of a total of what? Not
exactly like an NBC news broadcast. It didn't harm his reputation
at all. Most recognized that was not true up front, at least those
that know him or his program. That shrinks the group even further.

I write it off to the typical hyperbole that frequents this group.
Something minor happens, someone escalates it, someone escalates
that, pretty soon we are on the edge of mass genocide, or nuclear
war...

And after an apology is published, it gets even worse. Go figure...

I have indeed received a written apology from Jaap van den Herik, and have

Also, let me add that Crafty is quickly becoming something of a
"Standard" chess program across many platforms. And in many ways
I suspect that Crafty speeds up research/experiments into new
algorithms. Many times I have seen papers in ICCA giving data about
some new algorithm, but all that data comes from some program that
was written from scratch - and at times the program does not have the
current techniques (e.g. Null move) and one wonders about the data
they publish in the context a "real" program. With Crafty source
available, one can and probably should test his ideas in the context
of a "real" program.

The point maybe is, that Rolf and I are "famous" for our repetitions.
The second point is, that we "flag" red about Jaap, and suddenly, what
a nice synchronicity, this happens.

For me: I just laugh about it, and think: ha - thats karma !

Maybe Rolf is not so good in laughing about something....

Code they have written... like a command to make Crafty beep?

Trying to do something like this may be sillier than deciding who's
amateur and professional. We could even come up with a 25% rule for this,
as in 25% of the program must be original code.

I don't like the situation any more than you do, but it's been around for
a while and not caused too horrible a problem. GNU Chess was around long
before Crafty and a manageable number of clones played in tournaments. So
far Gunda is the only rip-off of Crafty that I know of, and Crafty has
been around for ~1.5 years, I think. That's an average I could live with.
If the problem starts getting noticably worse, then I'm totally in favor
of doing something about it, but I don't see that happening yet...

Cheers,
Tom

We learnt again that a worldwide heroe (in computer chess programming) could

PS. It's not that your statistics was wrong pointing out that one error could
not break a longtime good record. But to the not so friendly *ape* behavior
(mclane) there's this typical disgusting apology behaviour of the actual ICCA
officers. Their words simply stink through walls thicker than two meters of
stained steel at least ... If you can understand how angry I am. <big howling

And it's a tragedy seeing you waving the white sheet in front of them.

PPS.
Or was it blackmail?? Tell me, dear Bobby, what your actions really were for.
Together we're strong!
Let your bride and her constant insults on her iron bed, leave your place in
the hide under it and come to Europe. Here you could start a new life in
freedom. BTW, where did your anchestors come from? More Ireland or Bavaria?
It doesn't matter, we're just in train to build the new state of Europe.
If you start right now you could be here at the beginning of AEGON.

We all wait for you.

however, in the case at hand, it was negligence.

basically i don't buy your argument that the settlement is of
concern only between van den Herik and Manojararajah. for example,
supposedly the "settlement" provides that ICCA will publish an
article about RAJAH. that is a concern to all readers of the
journal, because the program might not otherwise be worthy of an
article. the association is forced to use resources (printing the
article) in order to make up for its mistakes. that is a valid
concern of the membership.

van den Herik was writing an article that talked about the giving
credit where credit is due. ironically, he himself failed to give
proper credit to someone (Manohararajah) in his article. when his
error was caught, he issued a lame apology blaming someone else.
so he also failed to accept blame where blame was due.

you complained about people fanning the flames, but you are
keeping this thread alive, by continually saying things like the above,
``It didn't harm his reputation at all.'' baloney. the article
wrongly put Manojararajah's program in the category that the article
identified as less deserving. moreover, the article used his program
as an EXAMPLE of the category.

>And after an apology is published, it gets even worse. Go figure...

it got worse because it was a totally lame apology. and because
you and other ICCA apologists continue posting such lame arguments.

first, we are not talking about just borrowing ideas. we are
talking about deriving one program from another. GUNDA didn't just
borrow ideas from CRAFTY. do you admit there is a difference?

second, i claim he likened it to plagiarism because after
discussing RAJAH and GUNDA he said:
``For articles, we do not allow plagiarism. For algorithms and
programs I believe we are in a state of flux.'' either he is
likening it to plagiarism or he is making a horrible non-sequitur.
notice i didn't claim he said it was exactly the same as plagiarism.
but there is clearly a suggestion that the two are conceptually similar.

if he wasn't likening it (the supposed derivation of RAJAH from
CRAFTY) to plagiarism, then what do you think he DID mean by this
juxtaposition?

well, he could issue a sincere apology accepting responsibility
for the mistake, no excuses.

but actually, the reason i'm continuing to write about this
is NOT because i really want HIM to do anything. the reason is
i want YOU and the other ICCA apologists to stop understating
the harm that was done to the author of RAJAH.

i suspect the difference is a lot smaller on the "receiving" end.

Wait. I think *everyone* agrees Jaap made a mistake. The question
boils down to the *degree* of the mistake. I still feel that it's a
minor issue in the overall scheme of things. Were I Manojararajah, I'd
be *more* upset about it, because it would be more personally related to
me. However, he's seemingly accepted the appology and has closed this as
a point of contention. Whether a page of a journal with a circulation
of 500 members is a big issue or not is open to discussion, but I don't
think it is a big deal. 1/2 page blurbs are there all the time. Most
anyone can write a letter to the journal, commenting on inaccuracies in
a prior article and the letters are published regularly, so this isn't
something new and expensive. It's another flavor of something that has
happened dozens of times before.

I think he simply told the truth. IE, you walk up behind a bunch of
computer chess enthusiasts talking (random names: me, Slate, Moreland,
Stanback, Kittinger, etc.) informally, you hear a couple talking about
a new program that is based on Crafty, and you report it. You might be
tempted to write that in a casual comment, as Jaap did, because you heard
it from a group that you are pretty sure knows what's going on. And you'd
be wrong. If you were writing about Rajah itself, you should certainly check
the sources of information carefully. But if you were writing about Crafty,
and you heard several make statements (let's take Gunda-1 at Jakarta) about
the program, you might work one of those statements in and then find it was
incorrect. Since the focus of his comments was not on Rajah, I consider it
less of an oversight than if he'd been writing a tournament results report
and printed that Rajah was a Crafty clone...

I'm looking at not only what he said, but where he said it, and the context
surrounding what he said... And he was (apparently) told that here's another
program that was derived from Crafty, so while mentioning Crafty I'll add this
as another case.

In that light, it is much less intentional, although still just as incorrect.

Sorry, commander, minor correction. Not completely true your historical review.
When you already jumped in with your satisfied laughs, I wasn't interested at
all.

Misch jeit un jing dae aap nix aan. :)
(That's an inner-german saying in the idiom of Cologne, called *koelsch* like
the beer.)

I'm interested each time proxies and god in person fly in to build a wall of
fog to hide these ICCA officers. This time BM took Fong's -- as always -- top
arguing. Remained our god. What Chris as expert could see with a glimpse, I
have still to work out a little bit. Bob is famous for his trying to shift and
corrupt the original content. He's very inventive in creating new
words/notions/assumptions.

Jaap did an *honest mistake.*
Aha, but when I myself did confuse unintentionally two ICCA VIP's and you
corrected me, the same god jumped up and down and justified the wish for
apologies with this terrible compairison with the case of a violated little
girl.

Two possibolities:

He's really that specialized on cc and minor educated in other spheres ...
Or he has a real motive connected with the ICCA and his officers ...
If you know what I mean ...
Problem with Bob is this certain discrepancy.

And I fear we have to discuss another topic earlier or later.
The academical carreer of top specialists.
If the normal growth of moral and human thinking is neglected in favour of a
said more important special talent you might observe this.
It's simply impossible to repeat in a fortnight hurry-up just for the
examinations the long-term education in democracy.

Also I would always applaude the late academical carreer of people. But these
shouldn't be taken for reference in fields they surely are as innocently
trained as anyone at the bus-stop.

You'll also find the same deficiency in *normal* academical specialists.
If you studied maths, natural sciences, jurisprudence or medicine especially,
you're not necessarily equally trained in political/moral/human thinking.
But if you studied the latter topics you're still not automatically *a better
human*.


Hey mclane, you see, here we are again. You remember the last thread where I
mentioned the importance of an educated elite and the *lost* innocent normal
people when they are forced to rely on academics and their titles ...?!

But if you allow each artist who's able to create ships out of zillions of
matches to become professor of informational vessel engineering and this man
jumps into politics you might kill every system.

Same thing with Hitler. If you buy each talented orator from the market-place
more so he's eidetically gifted, and enable him to foundate political parties,
you must be aware that he might fall in pieces in fundamental questions of
human life. At the end he says bye-bye and leaves you and the people in your
shit.

I named Hitler, but in today's multimedia world many more talented fakers could
win the masses. In US you could become a philosophical future politician just
by the record of your income. Look at Bill Gates. Also german media are greedy
of some of his words about *the* future. Although he did nothing but making a
new medium more -- others say *less* -- easier. That's ridiculous. No, it's
dangerous!

It's the same as if the chinese inventor(s) of paper later called himself or
WAS Kung Fu Dse. Would you believe this possible?


Tell me your opinions. Sometimes you seem to be a *natural born* all around
educated man of sciences. Flexible like a bunji cord. With or without official
titles ...

if you look at it that way, possibly. I read it differently: copying
words is one thing, but copying and modifying a program is completely
different, and we don't understand much about what it means, how to detect
it, if it is even wrong, and what to do about it if it is...

: if he wasn't likening it (the supposed derivation of RAJAH from


: CRAFTY) to plagiarism, then what do you think he DID mean by this
: juxtaposition?

No idea... I (personally) simply write exactly what I wrote right after I
discovered that we had two crafty's in jakarta. I didn't like it, because
I didn't think it was fair. I was pretty sure Crafty would play decent
chess, because it had thousands of games "under its belt." And I don't think
it's fair to enter a program twice, ala' the old days of Mephisto, Fidelity
and Saitek doing battle, rigging games and outcomes, and so forth. I don't
like the idea of "clones". I do like the idea of someone starting off with
Crafty and then going their own direction over time, as they will likely
end up with something very different. Gunda was likely not so different
however, as the time was too short.

I'm not sure what to do about this problem. I'm not even sure anything can
be done about it. And so I'll likely ignore it completely. If necessary I
can easily confirm that a program is a relative of crafty, even without the
source, because there are many binary "signatures" in crafty that would be
nearly impossible to remove without rewriting very complex parts of the
engine (the rotated bitmap stuff would be easy to find in a binary file
for example due to all the constants in the compact_attacks stuff.)

If you have ever read the JICCA, you will find a substantial amount of idle
rambling in the first page. Not meant to be insulting, but only factual. And
if you read enough of those, you might think (as I think) that he simply put
fingers in motion before putting brain in gear, and rambled off and said something
that he'd like to have back. I do it all the time. In here, usually. :)
