Owl Computer Chess Engines Rating List #15 - All Versions

The 15th Owl Computer Chess Engines Rating List published.  The changes are made from the completed gauntlet 4 rounds tournament games of Arasan 15.2 and Bison 9.11.  Arasan dropped from rank #71 to rank #78, while Bison managed to remain at rank #73.  There was no noticeable movement in the top 36 chess engines, probably because they have more games played, while the rest have changed ELO or shifted slightly from the ranks.  The bottom ELO rank owned by Ant 2009B has decreased from 1769 to 1739,  a big 40 points drop.  It is necessary that the chess engines with fewer games played must have more exposure to have a relatively stable ranking.
