Re: Unofficial World Championships Of Computer Programs Rapid 2019

I fixed some bugs and applied changes to the handling of isolated man (geisoleerde schijven) and locks (opsluitingen).
Apparently, it worked :)

Hi Krzysztof,

That are quite a lot of rounds!
Which hardware do you use for this tournament, the i7 or the AMD Ryzen?

Re: Coding issues

Hi Gérard, I would recommend using const which is not allocated in memory, but is followed by a type such that the compiler can perform type checking. Also I would recommend to use unsigned integers when doing bit mask operations. Actually this is more-or-less a must when you start to shift bits in ...

Re: Sjende Blyn - question

Hi Jelle. I have a question. Please write whether the Sjende Blyn program will be able to run without problems on the processor AMD Ryzen Threadripper 1950x. Thank you for information in advance. I assume it will, but to use all 16 wonderfull cores, you will need an update. I will send it to you by...

Re: The Unofficial World Championship Of Computer Programs In International Draughts 2018

I think that Gérard was referring to last year's discoveries. We established that Joost and the authors of Edeon Sport were using Scan's evaluation. Joost wrote about it openly on the forum. I am thinking whether or not the Edeon Sport program would use some function from the Scan program to by at ...

Re: The Unofficial World Championship Of Computer Programs In International Draughts 2018

Hi Krzysztof,

Is the Damage program a new program from Bert Tuyt?

After your tournament in 2017 there was discussion about whether Edeon Sport was illegally using Scan's evaluation (taxation of position). Any news on that?

Re: Computer Olympiad 2017 Draughts

Hi Jelle, Are you interested by knowing if (15-20) is a winning move or not? If yes did you find another white move in the line above on which white might reach a draw? It's a bit different: ... 15-20; 32-27 7-11; 16x7 12x1; 21x12 18x7; 30-25 33-38; 44-39 23-28; 45-40 and indeed likely for black to...
