Scratch Chess Engine - Game of Kings
I mean, if one day I do a connect 4 bot, I will.Connect 4 Bot Game SeriesWill you be running another Connect 4 tournament?
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

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).

Made some more adjustments to the search parameters, Wolverine's tactical play should be even stronger now.

I have stopped working on my Chess AI. I really don't like creating it.Noooooo! Too bad, it could have ended up really well. I at least hope you continue to work on your Connect 4 bot, it's a really nice project and it's pretty decent.

Yes. I am planning to create one in a text-based programming language after learning one.

the problem with text based programming langages is that you need to understand the concept of magic bitboards if you want it to be competitive lolYes.
