Freecell Solver version 4.2.0, has been released. It is available in the form of a source archive, from the download page. Freecell Solver is an open source library and some command line applications, for automatically solving several variants of card Solitaire / Patience games, including Freecell.
This release sports the new configuration theme “-l conspiracy-theory” (or “-l ct”) which is somewhat faster than the best contender up to it, “-l amateur-star”, some relatively minor bug fixes, new compile-time options, and many small and somewhat larger code cleanups, refactorings, and optimisations.
“conspiracy-theory” is a reference to the Jewish holiday of Purim, which took place around the time of its release and an old post of mine about it.
Enjoy!
