Functional Constraint Library

FaCiLe is a constraint programming library on integer and integer set finite domains written in OCaml. It offers all usual facilities to create and manipulate finite domain variables, arithmetic expressions and constraints, built-in global constraints and search and optimization goals. FaCiLe allows as well to build easily user-defined constraints and goals, making pervasive use of OCaml higher-order functionals to provide a simple and flexible interface for the user.
