A new version of FcPro updated to include Freecell Solver version 2.6.1
has now been made available in place of the former release usind FCS version
2.4.3.. It can be downloaded from
http://www.rrhistorical.com/rrdata/Fcpro65/ .
With regard to false impossibles, we had an interesting case of
serendipity here. We expected to get improvement in the false impossible
tendency from 2.6.1 only by use of the atomic move mode. As it turned out,
2.6.1 contained another improvement which greatly reduces its inherent
tendency to false impossibles, but did not eliminate it entirely. Instead
of the 185 false impossibles over the range of approximately 25,000
positions in our standard test, there were only three. The atomic move
option eliminates those.
As regards the speed competition between FCS and Patsolve, we must now
give the crown back to Patsolve. FCS is considerably slower -- by a factor
of at least five, when it operates in the atomic move (non-false-impossible)
mode. FCS's speed advantage over FcPro, in the false-impossible-prone mode,
however, is now more like three to one, with the improvements made in 2.6.1.
Further details are provided on the website.
