functional constraint library implemented in Objective Caml

FaCiLe is a constraint programming library over integer finite domain written in Objective Caml. It offers all usual facilities to create and manipulate finite domain variables, arithmetic expressions and constraints (possibly non-linear), built-in global constraints and search goals. FaCiLe allows as well to build easily user-defined constraints and goals (including recursive ones), making pervasive use of OCaml higher-order functionals to provide a simple and flexible interface for the user. As FaCiLe is an OCaml library and not "yet another language", the user benefits from type inference and strong typing discipline, high level of abstraction, modules and objects system, as well as native code compilation efficiency, garbage collection and replay debugger, all features of OCaml (among many others) that allow to prototype and experiment quickly: modeling, data processing and interface are implemented with the same powerful and efficient language.
