New chess engine - Ceibo

Postby federicorojo » Mon Dec 11, 2017 7:42 pm

Hello everyone,

I have created my own UCI chess engine and I would appreciate if anyone could have it tested. I have been working on it as a hobbie, whenever I have the time. It s been almost a year now since i started, but it is not a strong engine yet and i am hoping it will be some day. For now it supports transposition tables with sizes 1 to 128mb, set to 64mb as default, and also it has its own opening book that is enabled by default (uci command displays both of them). These can be changed via the 'setoption' command, but if needed or if it easier, I can default these values to anything else to meet whatever the test conditions are. If so, please let me know and i ll generate a new version with the changes.

I have attached a link to the exe below:

Please let me know if you have any issues with it.

Thanks! :)

Hi Fede

I try to disable book, even in arena debug windows appears like disabled but when I start a game Ceibo uses his book. And if you can change the hash size to 256 would be great.

Thank you

Hi Sergio,

Thank you for your response and for pointing out the defect when trying to disable the 'ownbook' option from Arena. The engine was resetting to default values every time a 'ucinewgame' command was sent to the engine. Its fixed now.

In any case, i have disabled the ownbook option by default, and also set a hash size to 256mb. The new version is 0.3.65 and you can download it from here:

Roughly how strong in CCRL terms do you expect Ceibo to be?

Hi Graham,
I would expect an ELO around or above 1800 but less than 2000. If it turns out to be less than that i'd be surprised. However, I always use short time controls such as 10+0.1 or 30+0.3, so I guess the result could be different to what i would expect.

Thanks, Fede
