Constraint-logic programming language based on LF Logical Framework; a uniform meta-language for specifying, implementing, and proving properties of programming languages and logics that is implemented as an interpreter in Standard ML.

Description and contact for runtime, compiler (byte-code), constraint solver; free for academic and research use.

Free, logic-based constraint solver: C++ implementation of implicit enumeration algorithm for solving (non)linear 0-1 (or pseudo-Boolean) optimization problems with integer coefficients.

A constraint describes a relation to maintain; it states what the relationship is versus how to maintain it. In many uses (interactive graphics, planning, document formatting, decision support), one must express preferences (soft constraints), and str...

Constraint logic programming (CLP) based language. Backtracking, advanced data types (including "Bignum") and data structures. IDE/Compiler for Windows 9x/NT/2000/XP.

Compares efficiency of 8 Constraint Logic Programming (CLP) systems in the setting of finite domains, and a specific aspect of their expressiveness: that concerning reification and meta-constraints.

Manual, Postscript (450K) or gzipped (130K), from University of New South Wales.

Technical reports on CLP at the Austrian Research Institute for Artificial Intelligence (ÖFAI) of the Austrian Society for Cybernetics.

Implementation of general Constraint Logic Programming scheme introduced by Jaffar, Michaylov 1987. As full as other CLP(R)s: solves linear equations over rational or real valued variables, and covers lazy treatment of nonlinear equations.
