List of chess engine rating sources
- List of chess engine rating sources
Chess engine rating sources are a number of highly specialized organisations or individuals that deal with measurements of the abilities of chess programs.
Rating lists use confidence interval estimates of chess engine strength, expressed in Elo rating points.
There is a number of factors that vary among the chess engine rating lists:
* Time control. Longer time controls, such as 40 moves in 120 minutes, are better suited for determining tournament play strength, but also make testing more time-consuming.
* Hardware used. Stronger hardware leads to stronger play.
* 64-bit (vs. 32-bit) hardware and operating system.
* Multiprocessor vs. single processor hardware.
* Ponder settings.
* Opening book settings.
These differences affect the results, and make direct comparisons between different rating lists difficult.
