Sam has closed his piano and gone to bed ... now we can talk about the real stuff of life ... love, liberty and games such as
Janus, Capablanca Random, Embassy Chess & the odd mention of other 10x8 variants is welcome too

O čem je toďten plk: Re: Vortex vs. S.M.I.R.F.

rabbitoid: I think after 48 hours, the hardware difference is negligible. The branching factor is such that almost any machine will get you to the same nominal depth. Say with all of your pruning tricks your software branching factor is 4, down from about 50 in the actual game.

That means if ply X completes at time T, ply X+1 requires 4T, X+2 needs 16T, X+3 64T, etc.

If the speed differential was a factor of 4, meaning one machine was 4 times faster than the other, even after 2 days, the faster machine would only outsearch the other by 1 ply.

I am sure Reinhard's hardware is within a factor or 2 of mine, maybe even less. I have a 2.8 GHz Pentium IV.
