Freecell Solver
Freecell Solver is a framework written in ANSI C to solve deals of Freecell and similar variants of card Solitaire. It is distributed as open-source software under the Public Domain.
Originally written as a way to test whether some ideas I had for solving Freecell programmatically would work, Freecell Solver grew to become a fast , versatile and portable program with many features, and has already been integrated into three Freecell implementations so far.
