Freecell Solver version 3.20.0, has been released. Freecell Solver 3.20.0 is available in the form of a source archive, from the download page. Freecell Solver is an open source framework (library and some command line applications), for automatically solving several variants of card Solitaire / Patience games, including Freecell.
The highlights of this version are some major optimisations to the solving code of Simple Simon, as well as many code cleanups, refactorings and smaller optimisations. Furthermore, the “qualified-seed-improved” preset was added, which yields shorter solutions.
