This simplifies slightly the code. This PR is a functionally equivalent refactoring of the version which was submitted. Four versions tried, 2 passed both STC and LTC. I picked the one which seemed more promising at LTC. Slope 4 passed STC (-0.54 Elo), LTC not attempted Slope 3 passed STC (+2.51 Elo), LTC (-0.44 Elo) Slope 2 passed STC (+2.09 Elo), LTC (+0.04 Elo) Slope 1 passed STC (+0.90 Elo), failed LTC (-3.40 Elo) Bench: 4761613 |
