elo -> ccrl

Post by OfekShochat »

Hello, I want to test my engine to a ccrl like elo estimate. how do I do that?
lets say my engine won 48% of the matches against a 3000 ccrl engine. is it (97%)(3000)?

There are a lot of online Elo calculators you could use, for instance:

I dont want the elo. I want to know if there is a difference from regular elo to ccrl elo.
if there is, what is it?

I mean, if there are more than one engine, do I need to store all the wins and games for every engine to every engine?

I think they use BayesElo: https://www.remi-coulom.fr/Bayesian-Elo/
If you really want to be sure ask one of the CCRL people.
