Hi, here is the result for Crafty15.20 on a 2xPPro 233 MHz: total acd: 2519 mean total acd: 11.66 total acn: -990304611 mean total acn: -4584743.57 total acs: 37850 mean total acs: 175.23 total mean node frequency: -26163.93 Hz solve: 145 solve percent: 67.13 solve acd: 1711 mean solve acd: 11.80 solve acn: 824256592 mean solve acn: 5684528.22 solve acs: 24994 mean solve acs: 172.37 solve mean node frequency: 32978.18 Hz unsol: 71 unsol percent: 32.87 unsol acd: 808 mean unsol acd: 11.38 unsol acn: -1814561203 mean unsol acn: -25557200.04 unsol acs: 12856 mean unsol acs: 181.07 unsol mean node frequency: -141145.08 Hz which means that crafty solved 145 from 216 within 3 min. Thats not too bad IMHO. Kind regards Bernhard
