Re: On-line engine blitz tourney November

I don't know. Normally one would not use settings files, just the -fUCI option on the GUI.

Hello! :D
I have this problem: "Startup failure on polyglot -noini...''"
Can you help with solving the problem? Thanks!
It sounds like you don't have Polyglot installed. What platform are you on anyway? Is this WinBoard + Windows, or XBoard + Linux or what?

Re: Any Fortran coder ?

I think I never got beyond Fortran 60 (or something like that), before I switched to other programming languages. Fortran 77 already appeared 'after my time'... Problem used to be that you couldn't do recursion; I don't know if later Fortrans fixed that.

Re: The Xiphos Material Evaluator

No, that is certainly not faster.

score = materialHash[materialKey & MASK];

will definitely be at least an order of magnitude faster than any loop you would need to sum up the material value of all pieces in a leaf.

Re: The Xiphos Material Evaluator

They don't slow the engine at all. They are just as instantly as simple material formulas, a single table lookup indexed by the material key. The material table takes care of the Bishop pair bonus, and you get drawn-end-game discounting as a free extra, plus any non-linear effect you might want. (Su...

Re: The Xiphos Material Evaluator

Compare this with the obscure imbalance formula used by Bob Hyatt in Crafty, or the esoteric quadratic formula use by Stockfish. Now try who it thinks is ahead with 3 Queens vs 7 Knights. :lol: Having the value of all pieces go up towards the end-game is a simple and usuful method for encouraging p...
