Rank-based outposts Introduce OutpostRank[RANK_NB] which contains a bonus according to the rank of the outpost. We use it for the primary Outpost bonus. The values are based on the trends of the SPSA tuning run with some manual tweaks. Passed STC: LLR: 2.96 (-2.94,2.94) [-1.50,4.50] Total: 27454 W: 6059 L: 5869 D: 15526 http://tests.stockfishchess.org/tests/view/5dcadba20ebc590256922f09 Passed LTC: LLR: 2.94 (-2.94,2.94) [0.00,3.50] Total: 57950 W: 9443 L: 9112 D: 39395 http://tests.stockfishchess.org/tests/view/5dcaea880ebc5902569230bc Bench: 4778405 ---------------------------- The inspiration for this patch came from Stefan Geschwentner's attempt of modifying BishopPawns into a rank-based penalty. Michael Stembera suggested that maybe the S(0, 0) ranks (3rd, 7th and also maybe 8th) can still be tuned. This would expand our definition of Outpost and OutpostRanks would be removed altogether. Special thanks to Mark Tenzer for all the help and excellent suggestions.
