A.I. rematch 2007
Posted:
Mar 19, 2007, 10:11 PM
The programs of Mark Mammel (USA) and Viktor Barykin (Russia) battled it out again. The first tournament was run by Nosovsky in Russia a few years ago and my program won 2 of 2 games. Now we played D-pente on the kurnik site, and Viktor's program came out ahead 3 games to 1. We first played two games of 1 minute per move which we split, then played two games of 3 minutes per move, and Viktor won both.
I'll try to post transcripts later, hey dweebo, wasn't there a way of posting annotated games, I forget where that is...

Game two: time limit 1 minute per move. Opening by Noesis, Goro2007 plays player 1 My program played an opening which is probably strong for player 1. At this position my program blundered by capturing at N12 instead of playing in the active area like N7. It was searching at 6-ply with VCT, and ran out of time after examining only one or two moves. K10,H10,H8,L11,K8,K11,J11,L9,M11,H12,J8,L8,L10,K9,L7,L8,M7,J10,H11
Goro went on to win with G8 and M6. K10,H10,H8,L11,K8,K11,J11,L9,M11,H12,J8,L8,L10,K9,L7,L8,M7,J10,H11,N12,G8,F8,M6,N5,M5,M4,M9

Game three: time limit 3 minutes per move. Opening by Goro2007, Noesis plays player 1
This was the closest game, a good battle. My program seemed to be in OK position here but did not keep initiative with J12 K10,L11,M12,J11,M11,M10,K12,M13,N9,K13,K11,L13,N13,L11,K9,K8,H13,L10,L9,M8,L9,J9,M9,O9,L7,O11,H10,J9,J12
Then Goro went on to win with O12. K10,L11,M12,J11,M11,M10,K12,M13,N9,K13,K11,L13,N13,L11,K9,K8,H13,L10,L9,M8,L9,J9,M9,O9,L7,O11,H10,J9,J12,O12,O10,P11,Q10,N12,K10,K8,L12,L10,F15,G14,L14,J10,K11,J8

Game four: time limit 3 minutes per move. Opening by Noesis, Goro2007 plays player 1
This opening by Noesis definitely gave p1 the advantage and Goro gobbled it up. K10,K11,H10,K9,H8,G11,H9,H11,J11,G12,F11,H11,F13,J10,L12,J10,L8,G10,G9,K12,F10,F9,J7,J9,G9

I think I agree with you Thad. I don't know if I would call it an "easy" win, but it looks like the move you mentioned should indeed be a win for P2.
Who was who at that point in the first game? It would be interesting to see at which "level" mm_ai chooses a different 4th move as Player 1.
Mark, when you put your AI into a competition like this for Pro-Pente, do you still use that same opening book from a few years ago for the opening? Have you ever thought about tightening it up?
How does your program choose openings for D-Pente?
>Who was who at that point in the first game? It would be interesting to see at which "level" mm_ai chooses a different 4th move as Player 1.
The opening (first four stones) was proposed Goro, and my program chose to be player 1. Goro was player 2 who did not find the winning move proposed by Thad. My program was thinking on level 6 with VCT.

Yes, it still uses the same old opening book. I should update it but that would require work
>How does your program choose openings for D-Pente?
After the first stone in the center, it looks ahead and tries to find the most "neutral move" for each of the next three stone placements. It did not do a good job of finding neutral openings, a D-pente opening library would be helpful.
The name of my pente program is not "Goro2007" Goro2007 is just a Kurnik nick.
We used rather slow computers (my program was running on Celeron 2.2GHz) for this tournament. And both programs had time trouble with limit 1 minute per move. If time limit 3 minutes Ninuki makes right #4 move - J10.
