I have made the following table. The first 7 plys are checked against crafty. Ply 8 needed 47 hours on a 500MHz Pentium III. I have started to calculate ply 9, but it will take approximately three months, so I don't know if I will be able to finish it. Luckily my program is restartable. Ply| Number of nodes | Total # nodes | # Nodes / Prev. # Nodes ---+-----------------+---------------+------------------------ 0 | 1 | 1 | term= 0, ill=0 1 | 20 | 21 | 20.000 term= 0, ill=0 2 | 400 | 421 | 20.000 term= 0, ill=0 3 | 8902 | 9323 | 22.255 term= 0, ill=0 4 | 197281 | 206604 | 22.161 term= 0, ill=461 5 | 4865609 | 5072213 | 24.663 term= 8, ill=15375 6 | 119060324 | 124132537 | 24.470 term= 355, ill=916789 7 | 3195901860 | 3320034397 | 26.843 term= 11183, ill=27695459 8 | 84998978956 | 88319013353 | 26.596 term= 446950, ill=1165178140 term = The number of endnodes occuring before the calulated ply caused by a mate or stalemate. ill is the number of illegal moves the program had to undo because the king would be in check. Note that some report these numbers with term added to the number of nodes. Regards Andreas Stabel
