Here's a tetris AI that uses 4 functions to assess/compute the score of a given position: https://github.com/LeeYiyuan/tetrisai, as explained there: https://codemyroad.wordpress.com/2013/04/14/tetris-ai-the-near-perfect-player/. The guy apparently used a genetic algorithm to determine the best value...

Very nice! Would it be straightforward to implement an AI that plays to tetris? Where the drawing of tetrominoes would be as random as possible (instead of the fake random function commonly used, which does not allow more than 7 or so tetrominoes to be picked without leaving the other different tetr...

*) How are the wins distributed over white wins and black wins? Does white have an advantage even in the random limit, and if so, how big is it? I can answer this without the need to check the results. The most probable games are the shortest ones. That's because the probability to play a particula...

I have taken a long hiatus regarding chess news, so I do not really know the current strength of Leela (looks like about SF 10 now). I do not know whether tsvetkov is still participating in this forum. Anyway, he taught us his style (years ago I tried it and could draw SF on my android phone with si...

I indeed messed up with the quoting part.
Now your points are, I hope, crystal clear.

OK, what you meant is that playing with a time control as opposed to fixed depth lets both engines search deeper in endgame positions. That is indeed true and fixing depth indeed artificially lowers the level of endgame play of both engines. I think you're again missing Ronald's point. In addition,...

I had generated 5-piece WDL+DTZ TBs for regular chess and suicide chess in 2005 with a similar compression scheme (based on "Re-Pair compression" followed by Huffman). The current generator is an almost complete rewrite which made the generator much faster and multi-threaded and which added many id...

Hello Ronald de Man, Could you describe the situation of end game tablebases when you started to work on the Syzygy ones? After the success of Gaviota tablebases which reduced a lot the size of files (due to compression I suppose), what made you think you could come up with something a bit different...

Wow, scary and not that surprising I'd say. I didn't know about these kind of experiments, but I'm an ignorant in psychology. Thanks for the link.

Interesting question. Maybe this thread has some relevant information: http://www.talkchess.com/forum/viewtopi ... w=&start=0.
