From b56a098cfb5b2ff2e34acda693f2d9878de48aec Mon Sep 17 00:00:00 2001 From: Marco Costalba Date: Mon, 14 Nov 2011 09:02:01 +0100 Subject: [PATCH] CLOP: Passed pawns weights tuning Tuned with CLOP against a pool of 3 engines. Result verified with a direct match: After 11720 games at 10"+0.1 Mod vs Orig 1922 - 1832 - 7966 ELO +2 (+-3.6) So no change in self match but if CLOP is right it should be a bit better against an engine pool.
