version 23.5-1 and 23.5-2 are simply two consecutive runs with the same version to provide a normal result. The rest of the tests are version 23.5R06 and were tested where the -n is the aspiration window (delta value in the code posted yesterday). 23.5R06-1 means the aspiration window was +/- 1 with delta=1. 1 and 2 are a bit low, and by the time it gets to 10, it is pretty optimal. Bigger doesn't seem to hurt at all up to +/- 3.0 pawns... I was expecting a better result in the 20-40 range, the reason I ran the big numbers was to produce some worse results so that there is a recognizable curve with a clear optimal value, and worse results on either side. Didn't get exactly what I expected, as you can see...
