Version 1.9 has been released on github. https://github.com/abulmo/Dumb/releases/tag/v1.9
A few bugs have been corrected (time loss using Fischer time control) and some enhancements.
Have fun with it...

Thanks Richard.

Dumber and Dumb have been sparring partners for my engine(s) since a long time now! Great ELO per line of code ratio! I have a lot of sympathy for that approach!

Elo. Please.

Very cool!

I think if you replace AB by MCTS you could shave off a few hundred lines even. But if strength remains the same is unknown (probably weaker)
But you would not need a TT - because the tree stores its scores in each node.
So the whole of AB could be replaced by one struct + the core MCTS algorithm.

An MCTS is a TT.

I just release version 2.0 of Dumb on Github https://github.com/abulmo/Dumb/releases/tag/v2.0
Dumb 2.0 is about 70 Elo stronger than versions 1.9 - 1.11, but still simpler (1150 line of code instead of 1185) with more (but still too basic) comments.

Can you compile it for commodore c64 ?!

No. I do not think a D compiler can target this old computer.

If you keep improving it and it keeps getting stronger will you change the name to Smart 1.0?
