Re: CCRL 40/15, 40/2 and FRC lists updated (17th October 2020)

Yes, can confirm, version 8.00 had an issue with repeating time control, used too much time at initial moves. I made some adjustments.
I guess it could have affected the ratings...

Re: Tucano 8.00 release.

Hey Gabor,
Yes, the command line option is "-syzygy_path". Also, just to confirm the UCI or WB option would be "SyzygyPath". Just the command line has the _.
Thanks.

Re: Tucano 8.00 release.

- Syzygy endgame tablebase support, using fathom probing tool, Special thanks to Jon Dart. - UCI protocol support. I recommend running as UCI engine from now on. Does that mean Tucano is not able to use the syzygy bases in WB mode? Or something else? EDIT: I have found a variable syzygy_path in the...

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: Ivanhoe plays singlecore in TCEC 13 !!

Regarding tucano, I looked at the code, and is not properly reporting the nodes count. Also the max hash is 1024 :oops: . Those should be addressed in future releases. This version 7.05 playing in TCEC had few updates related to time control, and few search tweaks. Hope this clarifies and won't gene...

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,...
