[Bug-gnubg] Feature Request: Gnu to use rollouts for playing

[Ian Shaw]

Over at bgonline there are some results of tests of eXtremeGammon
against Gnubg.

The XGRoller setting seems to clearly outperform Gnubg 3-ply over the
100 positions tested so far. 

I'd be interested in seeing how gnubg gets on with similar settings.
With variance reduction off (as per XGRoller), I'm sure that gnubg is
fast enough for the job.

The command "set player 0 chequerplay type rollout" and all related
commands for setting the rollout parameters exist, but are not
implemented. Hopefully the code can be taken from the rollout code
without too much trouble.

I think that XGRoller has demonstrated that modern PCs are fast enough
to perform such rollouts, which was not the case when gnubg was first
coded.
