This package contains the Objective Caml source code for a counter-model generator for propositional Gödel-Dummett logic. It is based on ideas developed in the following paper accepted to IJCAR 2004:

"Counter-model search in Gödel-Dummett logics"
Dominique Larchey-Wendling
LORIA-CNRS

A more pratical description of the algorithm is presented in the following paper accepted to the ENTCS electronic journal Disproving. It comes as a complement to the previous theoretical paper:

"Gödel-Dummett counter-models through matrix computation"
Dominique Larchey-Wendling
LORIA-CNRS

This is a prototype implementation. Just type "make" to compile the project. A command-line tool is then available: "cmodels". It reads formulae from standard input. An optional loglevel can be set by the [-log] option. The file "examples.ml" contains a list of commands to test the generator interactively under Ocaml. Consult this file for the syntax of formulae. The file COPYING details the origin of the different parts of the source code.

Do not hesitate to contact me at larchey@loria.fr for further information.
