Re: Ivanhoe plays singlecore in TCEC 13 !!

Yesterday I was watching the game between Deus-X and Tucano and noticed that Tucano shows an incredibly low speed (around 1 mnps, sometimes even lower), so I suspect it was only using one core. Also the configured hash (1024 Mb) seems very low for a lazy-smp engine with these long thinking times. M...

Re: texel tuning

You have to create a function to loop a range of values and keep the one that minimizes e. You can select the range values. Here is my code. double calc_min_k(void) { double k = 0; double i; double e; double s = 9999; for (i = -2; i <= 2; i += 0.1) { e = calc_e_main(i, tune_param_value, MAX_THREADS,...

Re: Enxadrista 1.00 Release - Instructional chess engine

Thanks again Carlos, I updated the description in github and included your twitch channel.
I think it is fine to just have an idea of the strength. Enxadrista won't be a competitive engine. I hope it can be a documentation reference for Portuguese speaking programmers.

Re: Enxadrista 1.00 Release - Instructional chess engine

Thank you very much Carlos. I appreciated.
If you don't mind, can I update the documentation and include those results?
I can link to your twitch to give the credits, ok?

Re: I'm not very happy with the do {} while() statement in C

C++ vs. C; OOP vs. Procedural; Global vs. Local. These are different and unrelated things. You can use C and write OOP. You can use C++ and use Procedural. You can use lots of globals or none, in C or C++. Whatever you do, never be religious about it. Writing code that has 0 global variable for the...
