The Java version of REDUCE.

[Ted Kosan]

Did anybody on this list know that there is a Java version of the
REDUCE computer algebra system available?

I recently checked a copy of REDUCE out of the REDUCE project's
repository to find information on how its pattern matching system
worked. While I was digging through its source code, I was very
surprised to discover that at some point in time a Java-based Lisp was
created for REDUCE called JLisp. Here is a copy of the Java version of
REDUCE:

Just type java -jar jlisp.jar to launch JLisp. Here is some input to
get you started

2+2;

factorize(x^105-1);

solve(log(sin(x+3))^5 = 8,x);

Here is a link to the the REDUCE manual and website:

http://reduce-algebra.sourceforge.net/manual/manual-pdf.html

http://reduce-algebra.sourceforge.net/

Anyway, REDUCE appears to be a fast, high-quality CAS and the fact
that it has a Java version has me wondering about the possibility of
combining it with MathPiper.

Markus, I am especially interested in hearing your thoughts on the
Java version of JLisp. It may be a better match for the needs of
GeoGebraCAS than MathPiper currently is.

This is a very old message ... 

though, via Reduce a came to MathPiper.

the link below is not available,it seems...

Myself am a (very) old Reduce  user (say in the 1970 .. 1990ties) ...  

Just now busy reading the 'starter' book about MathPiper

(and found e.g. Unassign has becom Unbind ;-).
