Many thanks to Ryan Pronk for moral support most part of match and to Christopher for organizing such an outstanding, attractive event along with "testing programs tournament". Who will be next in line to play against programs - Miki, Sergio ... any other kamikaze ?

I accomplished half of one my goals - had once program in loss.

Best Regards,

[Krzysztof Grzelak]

A big thank you for a match for Alexandera Moiseyeva. Thanks also for the Ryan Pronk, Edward Trace, Edgar Gilbert, and all developers in the program participated in the match.

Krzysztof Grzelak.

[Krzysztof Grzelak]

Alex write who is Miki, Sergio.

[Alex_Moiseyev]

Alex write who is Miki, Sergio.

Miki - reigning 3-moves and GAYP World Champion from Italy Michele Borghetti.

Sergio - Sergio Scarpetta from italy, GAYP ex World Champion and official WCDF Challenger for upcoming 3-moves World Title match in 2017. Sergio was watching few of our games during match and Miki came once.

Both believed to be the best players today

Thank you for the information Alex.

[Chexhero]

Congratulations to Alex on a very tough well fought match! Next up, 11-man program challenge!! Piece of "cake."

[chipschap]

The larger question: what do these results mean? I think the loss to Nexus was almost accidental (though only Alex can say for sure), and in any case it was in one of the tough ballots. I haven't looked very hard at Cake's win.

Do the results prove that computers are vastly superior? Certainly not. But in a drawish game such as checkers, there would have to be many more games in order to draw any sort of definite, defensible conclusion. Do the results show that the computer has an edge? Perhaps. But it's really hard to say.

What is clear, though, is that a top human player such as Alex can hold his own. I really don't think a lot of players could manage 7 draws in 8 games against the likes of Cake and KingsRow.

And it's worth saying once more: this was an exhibition of courage and sportsmanship of the highest level.

[Ed Trice]

A few comments I have:

First, congratulations to Alex. Given the speed of checkers programs today, combined with their opening books and endgame databases, they are almost playing with a "draw in hand." The opening books navigate almost every pitfall at the start, and once out of book, they can see a safe path to the end of the game. It is almost impossible to score a win for a human player.

Secondly, I am not the author of GUI Checkers, Jon Kruezer is. I only ported it to a native 64-bit app for higher performance, and I added my Perfect Play endgame databases to it. Ed Gilbert performed many additional modifications to make the program play Fischer Clock time controls through Checkerboard. He also rebuilt the opening book.

I see my name attached to GUI Checkers, and I want to make sure I am not given too much credit for it.

[Krzysztof Grzelak]

Thank you for the information Ed. This is what I could have corrected.

[Alex_Moiseyev]

Secondly, I am not the author of GUI Checkers, Jon Kruezer is.

Thanks Ed! I corrected my post.

Regarding "almost impossible to score a win for a human player " ... I had NEXUS in loss but missed a win. The program played strange, losing 16-20?? In Octopus but I was unable to take full advantage on this and let program get out.

So, my resolution after this match - I can do it better next time!

[Krzysztof Grzelak]

[Ed Trice]

So, my resolution after this match - I can do it better next time!

One of the things I am working on is very large perfect play databases (10 pieces). These databases require 2 bytes for every position, and there are over 8 trillion positions. It will take about 20 terabytes to store everything. But, one amazing thing, once completed, a program that searches and uses these positions with perfect play, will ALWAYS take the shortest path to a win. And, if it ever "walks into" a loss, it will always postpone the loss for as long as possible.

However, the program will need about 256 Gigabytes of RAM to run. This makes it impossible to "distribute" the program. What I plan to do is write an online interface where a user can make a move, then this move will be transmitted to my program on my supercomputer. When the program makes its move, it will make it back to the online interface.

What I think would be cool: Once completed, have a "cooperative match" where several top human players can plan their moves, talk out loud, come up with a consensus, then make their move based on what the group thinks is best. Then, make the move on the online interface, and have the monstrous computer come up with its reply. This way, we can have a very different kind of match: Best of humankind vs. the machine.

Maybe I could make it so that many people can log on and "watch" (their comments would be hidden from the players themselves). If anyone is a skilled online interface programmer, feel free to chat with me if something like this interests you.
