Freecell Solver is an open source (distributed under the MIT/Expat licence) library, written in C, for attempting to solve several variants of card Solitaire/Patience, including Freecell .
The logs directory contains the logs for solving the 4-freecell deals of Freecell dealt using the MS Freecell deal generation algorithm (see https://fc-solve.shlomifish.org/faq.html#what_are_ms_deals ) starting from 100 million (100,000,000) and hopefully going up to 1e9 (= a milliard).
To prepare the statitistics, install GNU make and type "make" or "gmake".
Then run perl summarize.pl to get the summary.
To see a list of impossible deals, run perl print-final-impossible-deals.pl .
