Subject: Rename ProbCut to Multicut
X-Git-Url: https://git.sesse.net/?p=stockfish;a=commitdiff_plain;h=333696318555004770f6d2acaae0eb743cc7e9de;ds=sidebyside

Rename ProbCut to Multicut

The teqnique used is actually MultiCut:

https://chessprogramming.wikispaces.com/Multi-Cut

And not ProbCut:

https://chessprogramming.wikispaces.com/ProbCut

No functional change.
