Subject: [6-1] Languages
Its assumed that you can find your way to common languages like
LISP, C++ or Prolog by doing a web search; what are listed here are
some other languages that AI researchers may find
interesting. [Because I had trouble finding a good prolog recently,
I've added some prolog listings here.]
XSB Prolog:
XSB is a Logic Programming and Deductive Database system for Unix
and Windows. It is being developed at The Computer Science
Department, Stony Brook University, in collaboration with
Katholieke Universiteit Leuven, Universidade Nova de Lisboa, and
Uppsala Universitet. http://xsb.sourceforge.net/
Amzi! Prolog + Logic Server:
"Embed Prolog rule-based components in C/C++, Java, Delphi, Visual
Basic, Web Servers and more. Develop Unicode and/or ASCII
logic-bases using the Windows interactive development environment
(IDE). Integrate them with ODBC databases. Deploy them with the
Logic Server Libraries. Extend Amzi! Prolog with your own
functions/libraries. For Windows, Linux, Solaris, HP/UX. Available
on any other platform with a custom port (see below). Royalty-free
runtime" http://www.amzi.com/products/prolog_products.htm
Free Academic, Personal & Evaluation License.
Mozart:
Mozart is an advanced development platform for intelligent,
distributed applications. The system is the result of a decade of
research in programming language design and implementation,
constraint-based inferencing, distributed computing, and
human-computer interfaces.
JEOPS - The Java Embedded Object Production System:
It's a project intended to give Java the power of production
systems. JEOPS adds forward chaining, first-order production rules
to Java through a set of classes designed to provide this language
with some kind of declarative programming. With that, the
development of intelligent applications, such as software agents or
expert systems is facilitated.
http://www.di.ufpe.br/~csff/jeops/
KIEV:
Kiev is a backwards-compatible extension of Java that includes support
for (amount other things) lambda-calculus closures (ie functional
programming) and Prolog-like logic programming. Please see
http://www.forestro.com/kiev/index.html
LAMBDA-CALCULUS-BASED LANGUAGES:
LISP's theoretical origins lie in Church's lambda calculus. A number of
new languages that fix some shortcomings of LISP's implementation of the
lambda calculus are Scheme (simpler and fully tail recursive), ML
(support for types using the typed lambda calculus;
cm.bell-labs.com/cm/cs/what/smlnj/sml97.html) and Hashell (like ML but
it implements lazy evaluation properly; www.haskell.org).
POPLOG:
POPLOG is a multi-language software development environment
providing incremental compilers for a number of interactive
programming languages, notably: Pop-11, Prolog, and Common Lisp.
http://www.cs.bham.ac.uk/research/poplog/poplog.info.html
CLIPS:
CLIPS is a productive development and delivery expert system tool
which provides a complete environment for the construction of rule
and/or object based expert systems. CLIPS is used throughout the
public and private community including: all NASA sites and branches
of the military, numerous federal bureaus, government contractors,
universities, and many companies. The CLIPS home page is:
http://www.ghgcorp.com/clips/CLIPS.html
SCREAMER:
Screamer is an extension of Common Lisp that adds support for
nondeterministic programming. Screamer consists of two levels. The
basic nondeterministic level adds support for backtracking and
undoable side effects. On top of this nondeterministic substrate,
Screamer provides a comprehensive constraint programming language in
which one can formulate and solve mixed systems of numeric and
symbolic constraints. Together, these two levels augment Common Lisp
with practically all of the functionality of both Prolog and
constraint logic programming languages such as CHiP and CLP(R).
Furthermore, Screamer is fully integrated with Common Lisp. Screamer
programs can coexist and interoperate with other extensions to Common
Lisp such as CLOS, CLIM and Iterate.
In several ways Screamer is more efficient than other implementations
of backtracking languages. First, Screamer code is transformed into
Common Lisp which can be compiled by the underlying Common Lisp
system. Many competing implementations of nondeterministic Lisp are
interpreters and thus are far less efficient than Screamer. Second,
the backtracking primitives require fairly low overhead in Screamer.
Finally, this overhead to support backtracking is only paid for those
portions of the program which use the backtracking primitives.
Deterministic portions of user programs pass through the Screamer to
Common Lisp transformation unchanged. Since in practise, only small
portions of typical programs utilize the backtracking primitives,
Screamer can produce more efficient code than compilers for languages
in which backtracking is more pervasive.
Screamer is fairly portable across most Common Lisp implementations.
It currently runs under Genera 8.1.1 and 8.3 on both Symbolics 36xx
and Ivory machines, under Lucid 4.0.2 and 4.1 on Sun SPARC machines,
under MCL 2.0 and 2.0p2 on Apple Macintosh machines, and under Poplog
Common Lisp on Sun SPARC machines. It should run under any
implementation of Common Lisp which is compliant with CLtL2 and with
minor revision could be made to run under implementations compliant
with CLtL1 or dpANS.
Screamer is available by anonymous FTP from
ftp.cis.upenn.edu:/pub/screamer.tar.Z

Subject: [6-4] Agent Modelling - Artificial Life
In addition to programs available free by anonymous ftp, we've
included some programs which are available by contacting the authors,
and some programs which charge a nominal fee.
Agent Modelling:
ANIMALS is a simulation system written by Toby Tyrrell,
<to...@castle.ed.ac.uk>, for his PhD thesis. The thesis examines the
problem of action selection when dealing with realistic, animal-like
situations: how to choose, at each moment in time, the most
appropriate out of a repertoire of possible actions. It includes a
description is given of a simulated environment which is an extensive
and detailed simulation of the problem of action selection for
animals. This simulated environment is used to investigate the
adequacy of several theories of action selection (from both ethology
and artificial intelligence) such as the drive model, Lorenz's
psycho-hydraulic model and Maes' spreading activation network, and
outlines deficiencies in each mechanism. Finally, it proposes a new
approach to action selection is developed which determines the most
appropriate action in a principled way, and which does not suffer from
the inherent shortcomings found in other methods. The thesis includes
a review and bibliography of existing work on action selection. The
thesis is available by anonymous ftp from
ftp.ed.ac.uk:/pub/lrtt/ [129.215.146.5]
as the files as.1.ps.Z, as.2.ps.Z, ..., and as.7.ps.Z.
The simulation software is also available from the same site, as the
file se.tar.Z. The simulation software was written in Suntools rather
than Xtools. It can be run only from SunView or OpenWindows. The
action selection problem modelled by the simulated environment
comprises 15 different `sub-problems' (getting food, reproducing, not
getting lost, being vigilant for predators, etc), many internal and
external stimuli, and 35 different low-level actions to select
between.
***ViewGen SCHEDULED TO BE DELETED FROM THE FAQ***
ViewGen (Viewpoint Generator) is a Prolog program that implements a
"Belief Ascription Algorithm" as described in Ballim and Wilks (see the
bibliography section on User Modelling). This can be seen as a form of
agent modelling tool, which allows for the generation of arbitrarily deep
nested belief spaces based on the system's own beliefs, and on beliefs
that are typically held by groups of agents. ViewGen is available by
anonymous ftp from
crl.nmsu.edu:/pub/non-lexical/ViewFinder [128.123.1.18] (user anonymous)
ftp.ims.uni-stuttgart.de:/pub/ballim [141.58.127.8] (user ftp)
as the file ViewGen.tar.Z. The theory of belief ascription upon which
it is based is described in detail in Ballim and Wilks, and a general
framework for attributing and maintaining nested propositional
attitudes is described in Afzal Ballim's dissertation which is
archived with the Viewgen program (in the files
ViewFinder-{A4/A5/US}.tar.Z,
the variable part indicating the format of the PostScript file).
The inheritance reasoner is in the file vf-hetis.tar.Z.
Implemented in Sicstus prolog, and hence easily convertible to
any Edinburgh-style prolog. Contact Afzal Ballim <af...@divsun.unige.ch>

One of the major institutions do Artificial Life research, The
Santa Fe Institute's web page has lots of information.
Swarm is a software package for multi-agent simulation of complex
systems, originally developed at the Santa Fe Institute. Swarm is
intended to be a useful tool for researchers in a variety of
disciplines. The basic architecture of Swarm is the simulation of
collections of concurrently interacting agents: with this
architecture, we can implement a large variety of agent based models.

Tierra is an artificial life system for studying the evolution of
digital organisms. Tierra consists of a virtual computer and its
operating system, whose architecture has been designed in such a way
that the executable machine codes are evolvable. This means that the
machine code can be mutated (by flipping bits at random) or recombined
(by swapping segments of code between algorithms), and the resulting
code remains functional enough of the time for natural (or presumably
artificial) selection to be able to improve the code over time.
Tierra runs on Unix, Win32, the Amiga and MS-DOS. Tierra's homepage is at:
http://www.isd.atr.co.jp/~ray/tierra/
The software can be downloaded from
alife.santafe.edu:/pub/SOFTWARE/Tierra [192.12.12.130]

(Chrome), GA (Pop) and problem (Problem) classes. The Problem class
is proposed as a portable representation for problems that would be
source compatible with a variety of other GP systems. GPQUICK uses a
steady state GA, tournament selection, one type of mutation, and
subtree crossover. It uses a fast, compact linear representation for
S-expressions. It includes documentation from the associated magazine
article (Byte, "Some Assembly Required", February 1994). GPQUICK is
available by anonymous ftp from
ftp.cc.utexas.edu:/pub/genetic-programming/code/
as the files gpquick.tar (unix version, tested with CC and g++) and
gpquick.zip (PC/ANSI C version, tested with Borland 3.1).

SNePS (Semantic Network Processing System) is the implementation of a
fully intensional theory of propositional knowledge representation and
reasoning. SNePS includes a module for creating and accessing
propositional semantic networks, path-based inference, node-based
inference based on SWM (a relevance logic with quantification) that
uses natural deduction and can deal with recursive rules, forward,
backward and bi-directional inference, nonstandard logical connectives
and quantifiers, an assumption based TMS for belief revision (SNeBR), a
morphological analyzer and a generalized ATN (GATN) parser for parsing
and generating natural language, SNePSLOG, a predicate-logic-style
interface to SNePS, XGinseng, an X-based graphics interface for
displaying, creating and editing SNePS networks, SNACTor, a
preliminary version of the SNePS Acting component, and SNIP 2.2, a new
implementation of the SNePS Inference Package that uses rule shadowing

MOBAL is a system for developing operational models of application
domains in a first order logic representation. It integrates a manual
knowledge acquisition and inspection environment, an inference engine,
machine learning methods for automated knowledge acquisition, and a
knowledge revision tool. By using MOBAL's knowledge acquisition
environment, you can incrementally develop a model of your domain in
terms of logical facts and rules. You can inspect the knowledge you
have entered in text or graphics windows, augment the knowledge, or
change it at any time. The built-in inference engine can immediately
execute the rules you have entered to show you the consequences of
your inputs, or answer queries about the current knowledge. MOBAL also
builds a dynamic sort taxonomy from your inputs. If you wish, you can
use several machine learning methods to automatically discover
additional rules based on the facts that you have entered, or to form
new concepts. If there are contradictions in the knowledge base due to
incorrect rules or facts, there is a knowledge revision tool to help
you locate the problem and fix it. MOBAL (release 3.0b) is available
free for non-commercial academic use by anonymous ftp from
ftp.gmd.de:/gmd/mlt/Mobal/
The system runs on Sun SparcStations, SunOS 4.1, and includes a
graphical interface implemented using Tcl/TK.

Set-Enumeration (SE) Trees for Induction/Classification. Significant
research in Machine Learning, and in Statistics, has been devoted to
the induction and use of decision trees as classifiers. An induction
framework which generalizes decision trees using a Set-Enumeration
(SE) tree is outlined in
Rymon, R. (1993), An SE-tree-based Characterization of the Induction
Problem. In Proc. of the Tenth International Conference on Machine
Learning, Amherst MA, pp. 268-275.
In this framework, called SE-Learn, rather than splitting according to
a single attribute, one recursively branches on all (or most) relevant
attributes. An induced SE-tree can be shown to economically embed many
decision trees, thereby supporting a more expressive hypothesis
representation. Also, by branching on many attributes, SE-Learn
removes much of the algorithm-dependent search bias. Implementations
of SE-Learn can benefit from many techniques developed for decision
trees (e.g., attribute-selection and pruning measures). In particular,
SE-Learn can be tailored to start off with one's favorite decision
tree, and then improve upon it by further exploring the SE-tree. This
hill-climbing algorithm allows trading time/space for added accuracy.
Current studies (yet unpublished) show that SE-trees are particularly
advantageous in domains where (relatively) few examples are available
for training, and in noisy domains. Finally, SE-trees can provide a
unified framework for combining induced knowledge with knowledge
available from other sources (Rymon, 1994).

* The ARS MAGNA abstract robot simulator provides an abstract world in
which a planner controls a mobile robot. This abstract world is more
realistic than typical blocks worlds, in which micro-world simplifying
assumptions do not hold. Experiments may be controlled by varying
global world parameters, such as perceptual noise, as well as building
specific environments in order to exercise particular planner
features. The world is also extensible to allow new experimental
designs that were not thought of originally. The simulator also
includes a simple graphical user-interface which uses the CLX
interface to the X window system. ARS MAGNA can be obtained by

helps control the domain and a graphical representation, but provides
relatively few constraints on the form of the domain and the agents'
abilities. Users may specify the time required by various activities,
the constraints on an agents' sensors, the configuration of the domain
and its properties, etc. MICE runs under XWindows on Un*x boxes, on

* Simderella is a robot simulator consisting of three programs: CONNEL
(the controller), SIMMEL (the robot simulator), and BEMMEL (the
X-windows oriented graphics back-end). SIMMEL performs a few matrix
multiplications, based on the Denavit Hartenberg method, calculates
velocities with the Newton-Euler scheme, and communicates with the
other two programs. BEMMEL only displays the robot. CONNEL is the
controller, which must be designed by the user (in the distributed
version, CONNEL is a simple inverse kinematics routine.) The programs
use Unix sockets for communication, so you must have sockets, but you
can run the programs on different machines. The software is available
by anonymous ftp from
galba.mbfys.kun.nl:/pub/neuro-software/pd/ [131.174.82.73]
as the file simderella.2.0.tar.gz. The software has been compiled using
gcc on SunOS running under X11R4/5 on Sun3, Sun4, Sun Sparc 1, 2, and
10, DEC Alpha, HP700, 386/486 (Linux), and Silicon Graphics
architectures. For more information, send email to Patrick van der
Smagt, <sm...@fwi.uva.nl>.
* RP1 is a Java-based robot simulator. It allows applications to build
arbitrary landscapes and a data-configurable robot which can interact with
a simulated environment or solve a virtual maze. The system provides
abstract features that model real-world objects such as walls, light
sources, and goals. For more information, see:

TimeGraph-- Metric and Qualitative temporal reasoning system which
handles (<, =, >) point relations, bounds on absolute
calendar/clock times, and bounds on durations. Data entry
and retrieval is through interval or point relations.
The system is scalable in the sense that storage
remains linear in the number of relations added.
Efficient retrieval is achieved through a simple
timepoint numbering scheme and metagraph structure.
See SIGART Bulletin 4 (3), pp. 21-25, July 1993.
Contact: Lenhart Schubert (schu...@cs.rochester.edu)
TimeGraph II (TG-II) handles the set of the relations of the Point
Algebra and of the Pointizable Interval Algebra (also called Simple
Interval Algebra by P. van Beek). Temporal relations are represented
through a "timegraph", a graph partitioned into a collection of "time
chains" which are automatically structured for efficiency. The system
is scalable, in the sense that the storage tends to remain linear in
the number of relations asserted. Efficient query handling is achieved
through a time point numbering scheme and a "metagraph" data
structure. TG-II is written in Common Lisp. For a description of the
theory underlying the system see:

Reasoning through Timegraphs", in Proceedings of IJCAI-93.

TimeLogic-- The TimeLogic system is an interval-based forward
chaining inference engine and database manager of
temporal constraints. Relational constraints,
indicating relative order between intervals, are based
on Allen's interval logic. The TimeLogic system also
supports durational constraints, indicating relative
magnitude between intervals, and reference links, used
for the explicit or automatic construction of interval
hierarchies. Constraints are posed and propagated in
user-defined contexts with inheritance. Supports relative
metric constraints but no absolute dates or times.
Written in Common Lisp.

TCNM (Temporal Constraint Network Manager) manages non-disjunctive
metric constraints on time-points and on durations in an integrated
way. These constraints allow us express absolute, qualitative and
metric constraints on time-points and on durations, which are managed
in an integrated way. In the updating processes, a non-redundant and
global consistent Temporal Constraint Network is always maintained by
means of an efficient and complete propagation method, with a O(n**2)
temporal complexity. Sound and complete retrieval processes have a
constant cost. Written in Common Lisp. For more information, contact

KEIM is a collection of software modules, written in Common Lisp with
CLOS, designed to be used in the production of theorem proving
systems. KEIM is intended to be used by those who want to build or
use deduction systems (such as resolution theorem provers) without
having to write the entire framework. KEIM is also suitable for
embedding a reasoning component into another Common Lisp program.
KEIM offers a range of datatypes implementing a logical language of
type theory (higher order logic), in which first order logic can be
embedded. KEIM's datatypes and algorithms include: types; terms
(symbols, applications, abstractions), environments (e.g., associating
symbols with types); unification and substitutions; proofs, including
resolution and natural deduction style. KEIM also provides
functionality for the pretty-printing, error handling, formula parsing
and user interface facilities which form a large part of any theorem
prover. Implementing with KEIM thus allows the programmer to avoid a
great deal of drudgery. KEIM has been tested in Allegro CL 4.1 and
Lucid CL 4.0 on Sun 4 workstations. KEIM is available for
noncommercial use via anonymous FTP from
js-sfbsun.cs.uni-sb.de:/pub/keim/keim*
