Chess 4.x only >did 2600 nodes per second as it won most of the 1970's events... How effective were those 2600 nodes though? Pioneer took several Hours (3:45:00) on a Nadareishvili Study , most programs solve this with millions of nodes instead of 200 like Pioneer! How fast would Chess 4.x be on todays hardware? Can someone get a copy a test it against Crafty or some other program? I mentioned Ostrich but i was confused i am really looking for information about Chaos. Chaos played some extreemly impressive moves for instance: Chaos - Chess 4.0 [D] rq2k2r/3n1ppp/p2bpnb1/8/Np1N4/1B3PP1/PP2Q2P/R1BR2K1 w kq - 0 1 16.Nxe6!! Chaos took 587 seconds to find this move it was searching 4500 nodes every 3 minutes or about 25 a second. Hiarcs 7.32 found this at 10/30 ply and 56.595.000 nodes 17:36 Gandalf found this at 7ply 5 seconds 450,000 nodes Chaos was on a UNIVAC 1110 it looked at only 14,675 nodes this was on an extreemly slow computer by todays standards and it would probably take a second.
