Chess Engines Grand Tournament, also known as CEGT, is one of the best-known organizations that tests computer chess software by playing chess programs against one another and producing a ratings table.
CEGT routinely tests amateur and professional chess engines in various time controls such as 40/4 (40 moves in 4 minutes, repeating), 40/20 (40 moves in 20 minutes, repeating), and 40/120 (40 moves in 120 minutes, repeating). The 40/120 matches were at one time considered some of the best computer-chess games freely available online, but the list has not been updated since March 2010.
As of September 2009, the testers team is composed of eight members co-ordinated by Heinz van Kempen, using a total of 20 personal computers. The team has run more than 480,000 games for 40/20, and more than 750,000 games for 40/4 (Blitz). Games include SMP testing.
As of 10 February 2011 (2011 -02-10), Houdini leads the 40/20 rating list standings with 3281 (two CPUs, testing in progress). The second place engine behind other versions of Houdini 1.5a is Deep Rybka 4 with 3246 (six CPUs). The best single-CPU engines are Houdini 1.5a at 3211, and Rybka 4 Exp 61 at 3146.
Famous quotes containing the words chess, engines and/or grand:
“Remember...that each child is a separate person, yours forever, but never fully yours. She can never be all you wished or wanted, or all you know she could be. But she will be a better human being if you can let her be herself.”
—Stella Chess (20th century)
“America is like one of those old-fashioned six-cylinder truck engines that can be missing two sparkplugs and have a broken flywheel and have a crankshaft that’s 5000 millimeters off fitting properly, and two bad ball-bearings, and still runs. We’re in that kind of situation. We can have substantial parts of the population committing suicide, and still run and look fairly good.”
—Thomas McGuane (b. 1939)
“Seeing to it that a youngster grows up believing not just in the here and now but also in the grand maybes of life guarantees that some small yet crucial part of him remains forever a child.”
—Anne Cassidy (20th century)
