Thanks for the information. I am pretty sure I saw Philippe Michel at
one point mention information regarding his findings with profiling. My
understanding that the random number generation (with MT) isn't much of
a bottleneck within the context of rollouts.
For each move happening in a 2ply rollout, there are 2 random numbers
generated and thousands of positions evaluated, leading to something like:
% cumulative self self total
time seconds seconds calls s/call s/call name
30.53 146.78 146.78 296200881 0.00 0.00 EvaluateSSE
...
0.00 480.84 0.00 19518 0.00 0.00 RolloutDice
For Oply, the discrepancy is smaller but the cost of random number
generation is still negligible.
