It simply did not play enough games(only 20 games) and older versions of sjeng were not tested.

Re: Programmer bug hunt challenge

I do not understand the bug

There was no enpassent capture possible in the end of the first game

There was no black pawn at b4 in the final position of the game.

Re: Is it time to make chess tiger free engine

The only question is if it is legal to do it without releasing the source assuming that fabien agree to it but if it is legal that fabien makes money from changing fruit without releasing the source then I see no reason to think that it is illegal that other people make money assuming that there is...

So, what is best, limiting each square to a maximum or adding up all the squares and scaling them...

Re: Is it time to make chess tiger free engine

unless chess tiger can make another 100 pt. leap, perhaps it is time to retire and live the good life like ed. He was one of the wisest of all, first he retires then improved an already great engine, allowed others, his code, and is now immortalized as an icon in computer chess history. Chess tiger...

Re: UCI Engines Ligue updated

I believe that progress 10 10 10 is better than the default personality(progress1 progress2 progress3 are uci parameters in movei). It can be good if you can test this personality in the uci league. Uri Hi Uri, We use mostly the default parameter. For each engine, there is one rating. So for Movei ...
