Freecell Solver 3.12.0

Freecell Solver version 3.12.0 has been released. It 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 first item to note is that the URL of its site changed from under * to, and that there is a redirect in place. Moreover, we have switched the version control system from one based on Subversion to a git repository which is currently hosted on GitHub (though we may move it later).

This release adds a new flag - --show-exceeded-limits or -sel for short, that removes some ambiguity in the output, and fixes a problem with starting the solver with --set-pruning r:tf in conjunction with -opt. A new preset - -l three-eighty (or -l te for short) has been added, which provides somewhat better performance.

The experimental dbm_fc_solver is now less experimental and can now store the positions inside binary trees in memory, and its memory consumption has been greatly reduced since earlier versions. We also added another experimental solver called fcc_fc_solver which aims to determine the solvability of a deal by analysing fully-connected-components (“FCCs”).

We also added support for building and testing the distribution in an out-of-tree build, and there are some cleanups to the code.

More information about all these can be found in the distributed documents of Freecell Solver.
