Note that in Crafty I did perf, not perft. These numbers should be just
generating moves only, not make/unmake. That's my understanding anyway, unless
Bob or Deiter wants to correct me on that. Anyway, here is what I get from the
'speed' command in Yace.
white ( 1): speed
eval: 785525.4 calls/s, 1.273 us/call
ataks: 1647361.6 calls/s, 0.607 us/call
incheck: 25344683.8 calls/s, 0.039 us/call
inck_lm0: 12664189.2 calls/s, 0.079 us/call
inck_lm1: 13255042.2 calls/s, 0.075 us/call
inck_hm0: 25658372.7 calls/s, 0.039 us/call
inck_hm1: 25354787.3 calls/s, 0.039 us/call
inck_hm0: 25683954.3 calls/s, 0.039 us/call
inck_hm1: 25343322.7 calls/s, 0.039 us/call
movelist: 2281586.2 calls/s, 0.438 us/call, 45631724.7 mv/s, 0.022 us/mv 20
Mum(nc): 828387.1 calls/s, 1.207 us/call, 16567742.1 mv/s, 0.060 us/mv 20
caplist: 3157859.7 calls/s, 0.317 us/call
Mum(c): 219756518.7 calls/s, 0.005 us/call
I'm not 100% sure what all of this means, but I can make some guesses that make
sense. I got my number from the 'movelist' line (45631724.7 mv/s). I assume
'Mum' means 'Make, UnMake', so I also assume 'movelist' doesn't do any
make/unmake. The Mum numbers are approximately what you get from running perft
in Yace. AFAIK, the public version of Yace doesn't use hash tables for perft. My
best guess for what the (nc) and (c) means after Mum is 'no captures' and
'captures', I guess.
