Re: Elo Gains from thinking on your opponents time

I am replying to Professor Hyatt's response: ..."so you get something in the 15-20 Elo range overall..." If I understand the math behind the expected value of results with ELO rating differences, this would mean that the modified engine, always analyzing, would win 2 - 3% more games than the unmodif...

When I run matches, the engine that is analyzing the next move takes up 98-99% of cpu usage while the other engi...

Can we learn anything from PGO compiled executables?

Can we learn anything from PGO compiled executables?

Code examples of saving evaluations

I have a lot of ideas and intend to have code save evaluations and proposed continuations to a file.

Here is an example: My engine...
