Probabilistic Reasoning:

   BELIEF is a Common Lisp implementation of the Dempster and Kong fusion
   and propagation algorithm for Graphical Belief Function Models and the
   Lauritzen and Spiegelhalter algorithm for Graphical Probabilistic
   Models. It includes code for manipulating graphical belief models such
   as Bayes Nets and Relevance Diagrams (a subset of Influence Diagrams)
   using both belief functions and probabilities as basic representations
   of uncertainty. It is available by anonymous ftp from

      ftp.stat.washington.edu [128.95.17.34]

   and by email from the author, Russell Almond <almond@stat.washington.edu>.
   Contact the author at almond@statsci.com for information about a
   commercial version GRAPHICAL-BELIEF currently in the prototype stages.

   IDEAL is a LISP system developed for building and evaluating influence
   diagrams and Bayesian networks.  It is accompanied with a graphical
   user interface (CLIM-based) for constructing, editing, and solving
   belief networks and influence diagrams. For more information, write
   to srinivas@rpal.rockwell.com.
