Connect 4 Bot Game Series

I am conducting a Connect 4 Bot test game series played by Game of Connect (GoC).

The results will be updated in this posting over time. They will cover the Scratch runtime and TurboWarp (TW only if an engine takes advantage of the additional performance there), with both sides as starting players once (as far as the projects allow). When several playing levels exist, games will be played on highest level available for the runtime.

The Bots

Scratch 3

Starting Side       Responding Side

GoC              -  CFAI (BirdRacer)     1  -  0    (win at ply 41)
GoC              -  C4AI (Spentine)      1  -  0    (win at ply 29)
GoC              -  C4AI-GL (PullJosh)   1  -  0    (win at ply 25)
GoC              -  OC4 (AKOS)           1  -  0    (win at ply 33)
GoC              -  OC4VC (ABC)          1  -  0    (win at ply 31)

CFAI (BirdRacer) -  GoC                0.5  -  0.5
C4AI (Spentine)  -  GoC                  0  -  1    (loss at ply 34)

TurboWarp

Starting Side       Responding Side

GoC              -  CFAI (BirdRacer)     1  -  0    (win at ply 31)
GoC              -  C4AI (Spentine)      1  -  0    (win at ply 39)

CFAI (BirdRacer) -  GoC                0.5  -  0.5
C4AI (Spentine)  -  GoC                  0  -  1    (loss at ply 42)

Note: GoC and BirdRacer's CFAI are think-time bound, hence not deterministic. They will play according to system speed (means, better on faster systems).

Thanks, pretty cool!

One question, on which level did you play, and how fast is your system? Because GoK's mistake at move 43 is discarded after 12 seconds on my system.

Pretty slow, I can't tell you the exact details as I got a new (hopefully faster!) computer a few days ago.

About the connect 4, would it be feasible for a depth-21 engine (i.e. fully solved game) on scratch? It is much simpler than chess after all.

Also have you thought about chess variant engines on scratch? Atomic would be pretty cool.

GoC (turbowarp) lost to Fairy Stockfish (15sec/move) in 19 moves (GoC went first), can’t post the moves as the filter blocks it though (probably the spaces). I’ll try and share the game a different way later.

You refer to Connect 4?

It's worth noting that Fairy Stockfish doesn't play perfectly. In a 15sec/move game with FStockfish facing itself, the result was a draw.
