Another suicide checkers match

[Martin Fierz]

I got another challenge for a suicide checkers match, this time from the east: Igor Korshunov, author of a strong chess program (WildCat) and of the Russian draughts program Kallisto, has challenged Suicidal Cake to a couple of games against his suicide checkers program.

We will play on Tuesday, April 25, 20:30GMT on Kurnik in the room Warkaly.

cake_author vs. SuicideKallisto

I don't know what to expect since I don't know any details of Igor's program. I do know that his chess program is much better than mine - he certainly knows something about game programming!

you have a chess program?

will games be saved?

could your suicide program be used to make some sort of book
on that style of checkers? i dont know of any book for that? i mostly mean as far as openings go

hi patrick

my chess program is in hibernation mode
i don't have enough time to work on it.

as far as the suicide program is concerned, there are some infos on it here: http://www.fierz.ch/suicidecheckers.php

Express news.

Kallisto with smaller ending database and without opening book won 3-0 against Cake. To the best of my knoweldges, this program (for Suicide Checkers) was written about 2-3 weeks ago.

The Russian programmer posted on Russian checkers forum information about score and quoted Martin Fiertz: "SuicideKallisto demonstrated a far superior understanding of the game and completely destroyed my program".

I hope we can hear soon from Martin "inside story" and details. Congratulations to both programs and programmers.

Regards,

Alex

aloha!

indeed, that is what i said - it was painfully obvious that igor knows something about suicide checkers that i don't. during our chat he said "kallisto does not evaluate material" while suicidal cake mainly relies on material evaluation. i'll post the games on my website soon, with a small writeup of the match.

BTW, kallisto won 4-0, as game 4 transposed into game 2 after 3 moves, and i resigned immediately. igor didn't want to win this way, but i didn't accept his generous offer to play another game.

in my defence, i spent very little time on suicidal cake ever, a day or two maximum. i just reversed the signs of the evaluation for wins/losses in cake, and built an endgame database and an opening book. the last two things are very simple once you have them for regular checkers. the book generator is in fact identical, while the endgame database generator needs changes to two lines of code. igor programmed kallisto in only 2 weeks, but before he had written a russian suicide checkers program, and obviously knows something about suicide checkers that i don't
that is worth much more than a lot of programming time!
