MEA is a tool (written by Ferdinand Mosca) that analyses an EPD position set in STS-style assigning bonus points pre-defined in each EPD record.
temere.epd (Latin for random) is a 4975 position set created from a much bigger random EPD collection in an intelligent way with as goal to produce a reasonable reliable ranking list of engines with an estimated error bar of -25/+25 elo at fast time controls like 100ms, 250ms, 500ms etc.
Examples
EPD | Time Control | Comment |
100ms | Many engines don't obey the 100ms time control, either they play too fast (blue color) or use too much time (red color). It's therefore a bit hard to interprete the rankings. But things get better and better when we increase the time control. | |
250ms | Xiphos and Schooner start to climb but still move too fast. | |
500ms | The rankings are starting to make more sense. | |
one second | Poor Pedone, but the close agreement of rank-4 till rank-8 with the CCRL list is truly amazing! |
Operation
1. Double click run-temere and watch the result. It takes 4 engines of equal CCRL strength (good old Ruffian, Wildcat, Rotor and Igel) and if it's good they will produce a reasonable close percentage.
2. Modify run-temere.bat to add the engines of your choice.
Hints:
• set MT=100 means move time in millieseconds.
• Make set MRL equal to the EPD filename as in the example.
3. Aside from the automatic browser update after each run a copy in text format is created for easy sharing results, see temere.txt.
