[6-3] Publicly Redistributable Lisp Software
AI Algorithms and Tools:
PAIL (Portable AI Lab) is a computing environment containing a
collection of state-of-the-art AI tools, examples, and documentation.
It is aimed at those involved in teaching AI courses at university
level or equivalent. The system has enough built-in functionality to
enable its users to get practical experience with a broad range of AI
problems without having to build all the supporting tools from
scratch. It is implemented in Common Lisp and uses CLOS and Allegro
Common Windows (i.e., in Allegro CL 4.1). It is available by anonymous
ftp from pobox.cscs.ch (148.187.10.13) in the directory /pub/ai/pail-2.1/.

AI_ATTIC is an anonymous ftp collection of classic AI programs and
other information maintained by the University of Texas at Austin. It
includes Parry, Adventure, Shrdlu, Doctor, Eliza, Animals, Trek, Zork,
Babbler, Jive, and some AI-related programming languages. This
archive currently resides on the host ftp.cc.utexas.edu
(bongo.cc.utexas.edu, 128.83.186.13) in the directory /pub/AI_ATTIC.
For more information, contact atticmaster@bongo.cc.utexas.edu.
The Automatic Memoization Facility adds a practical memoization
facility to Common Lisp. Automatic memoization is a technique by which
an existing function can be transformed into one that "remembers"
previous arguments and their associated results, yielding large
performance gains for certain types of applications. This facility
extends the ideas from Norvig's book into what is needed for a
practical tool for us in large programs. It adds facilities for
bookkeeping and timing, and lets you evaluate of the timing advantages
of memoization, and save hash tables to disk for automatic reuse in
later sessions. The code is available by anonymous ftp from
archive.cs.umbc.edu:/pub/Memoization [130.85.100.53]. Contact Marty Hall
<hall@aplcenmp.apl.jhu.edu> for more information. The code includes an
overview of memoization and its applications.
Benchmarks:

Vaughn Pratt), DESTRU (a destructive operation benchmark), DIV2 (a
benchmark which divides by 2 using lists of n ()'s), the FFT benchmark
written by Harry Barrow, FPRINT (a benchmark to print to a file),
FRPOLY (a Franz Lisp benchmark by Fateman based on polynomial
arithmentic), Forest Baskett's PUZZLE benchmark (originally written in
Pascal), the TPRINT benchmark to read and print to the terminal, a
benchmark that creates and traverses a tree structure, and TRIANG
(board game benchmark). Some of the benchmarks may work only in Lucid.

release. The UMass research system remains available, but the
two should not be confused as the commercial system is
substantially improved and extended. The commercial system is available
from Blackboard Technology Group, PO Box 44, 401 Main Street,
Amherst, Massachusetts 01002, 413-256-4240.

COLAB (COmpilation LABoratory) is a hybrid knowledge representation
system emphasizing the horizontal and vertical compilation of
knowledge bases. It is comprised of cooperating subsystems -- CONTAX,
FORWARD, RELFUN and TAXON -- which deal with different knowledge
representation and reasoning formalisms. Each subsystem can also be
used as stand-alone system. CONTAX deals with constraint nets and
constraint-propagation techniques. Relational knowledge in the form of
Horn rules is processed by forward (FORWARD) and backward (RELFUN)
chaining. Taxonomic knowledge is represented by intensional concept
definitions which are automatically arranged in a subsumption
hierarchy (TAXON). The COLAB software was developed at DFKI and the
University of Kaiserslautern and runs in Common Lisp. (The subsystems
have been tested in AKCL and Lucid CL, and possibly also Allegro CL
and Symbolics CL.) All the subsystems are available free of charge for
research purposes.
