Thanks for the file! This should be very helpful when I try to reproduce results.
It looks like you are not taking advantage of symmetries. For instance, 88|0|17.033168 88|1|12.263955 and 164|0|17.388714 164|1|25.862695 Are identical except for swapping the roles of white and black (88 == 1120 in base 4, 164 == 2210 in base 4), and therefore they should have the same scores. If you do take symmetries of this type into consideration, you'll reduce the number of gamma values you have to compute by a factor of almost 16 (8 symmetries in the D4 group, times 2 colors). This should result in faster learning and better estimates. Álvaro.
