For nearly two years Stefan Meyer-Kahlen has been leading the SSDF
Rating List with different versions of his program Shredder. But on
this first list of 2006, Shredder 9.0 UCI has dropped to the third
place.
One point ahead, on place two, comes Fritz 9.0 A1200 MHz with 2819 after
587 tournament games. During several earlier years Frans Morschs program
dominated in the top of the SSDF list. Fritz 9.0 didn't reach the first
place today, but it's rating is 38 points ahead of it's predecessor.
On the first place comes a program which never before has competed on
the SSDF Rating List! It's Fruit 2.2.1 A1200 MHz written by Fabien Letouzey
from France! After 457 games Fruit 2.2.1 has 2852, 33 points ahead of
Fritz 9.0! In August last year an earlier version of Fruit came on the
second place of the WCCC in Reykjavik.
It's fascinating that it's still possible to improve the playing strength of
chess programs, measured on the same hardware! I'm looking forward to see
what other programmers, newcomers and veterans, can achieve during 2006.
Lately we have tested some chess programs from Richard Lang and Christophe
Théron running on handheld computers or mobile phones. Now Mark Uniacke has
entered this trade with Hiarcs 9.5a/9.6 on a Palm Tungsten E using a OMAP-
processor on 126 MHz. This combination of chess program and hardware has
achieved a rating of 2391 based on 129 games! That is so far the highest
rating among non-PC entrants!
During the latest years SSDF hasn't published as many rating lists as we did
before. How it will be in the future is hard to know, but at least I can say
that our present testing capacity is as good as before, with seven testers
using ten pairs of PCs for evaluating the playing strength of chess programs.
During the nearest months we hope to find out how strong Hiarcs 10 and Rybka 1.2
are.
