Experiments and curiosities
90% of coding is debugging, the other 10% is writing bugs.

Re: Experiments and curiosities
Hi Ed!
I get similar results when running fixed depth matches between Wasp3 and Stockfish 8. Wasp wins 96% against SF at depth=4
I didn't test at higher depths, but of course SF will soon start to dominate Wasp. Fixed depth tests against other strong engines are somewhat similar also. I guess SF plays so weak at low depths due to it's huge amount of pruning and reduction. But I haven't found pruning and reduction conditions for Wasp that give enough reduction in tree size to offset the mistakes ....

Re: Experiments and curiosities
I ran some tests with SF8 (cfish) on Mac IIsi (MC68030 @20Mhz), which at 40/120 time control would reach between 6 and 12 ply depths, depending on the position. I ran it against Crafty, running on another machine at fixed depth 9 (moving instantly of course). There seemed to be some parity in strength there. Some estimated SF8 on that hardware at around 2600 Elo based on average NPS (300-400) over those games.jstanback wrote: ↑Wed May 16, 2018 11:07 pm Hi Ed!
