Re: In Praise of The King
on my mac, Crafty25-2 found the mate in 14 in less than 2 seconds, using one core.JVMerlino wrote: ↑Sat Aug 18, 2018 8:13 am The King still surprises me sometimes. This is v3.12, from Chessmaster 9000 in 2002, on old hardware, getting around 585KNPS, and finding a mate in 15 in four seconds. I tried several other engines, and only Crafty 25 (JA build) came close at 7 seconds (at 1 core, like The King), even though it needed more than 10x the nodes. To be fair, Crafty did improve to Mate in 14 much faster than The King did.

Re: In Praise of The King
on my mac, Crafty25-2 found the mate in 14 in less than 2 seconds, using one core.JVMerlino wrote: ↑Sat Aug 18, 2018 8:13 am The King still surprises me sometimes. This is v3.12, from Chessmaster 9000 in 2002, on old hardware, getting around 585KNPS, and finding a mate in 15 in four seconds. I tried several other engines, and only Crafty 25 (JA build) came close at 7 seconds (at 1 core, like The King), even though it needed more than 10x the nodes. To be fair, Crafty did improve to Mate in 14 much faster than The King did.
