King Psqt: 1)King will be encouraged more to stay in the first ranks in the MG 2)and will be encouraged more to go to the middle of the board/last ranks in the EG Bishop scale better in EG Logical changes on various psqt tables 1/6 of the changes of the last tuning session on mobility tables STC: LLR: 2.95 (-2.94,2.94) [0.00,4.00] Total: 227879 W: 41240 L: 40313 D: 146326 LTC : LLR: 2.95 (-2.94,2.94) [0.00,4.00] Total: 167047 W: 21871 L: 21291 D: 123885 Bench: 5695960 Closes #1008 --- diff --git a/src/evaluate.cpp b/src/evaluate.cpp index 6cd33bd5..62620a77 100644 --- a/src/evaluate.cpp +++ b/src/evaluate.cpp @@ -119,19 +119,19 @@ namespace { // indexed by piece type and number of attacked squares in the mobility area. const Score MobilityBonus[][32] = { {}, {}, - { S(-75,-76), S(-56,-54), S( -9,-26), S( -2,-10), S( 6, 5), S( 15, 11), // Knights - S( 22, 26), S( 30, 28), S( 36, 29) }, - { S(-48,-58), S(-21,-19), S( 16, -2), S( 26, 12), S( 37, 22), S( 51, 42), // Bishops - S( 54, 54), S( 63, 58), S( 65, 63), S( 71, 70), S( 79, 74), S( 81, 86), - S( 92, 90), S( 97, 94) }, - { S(-56,-78), S(-25,-18), S(-11, 26), S( -5, 55), S( -4, 70), S( -1, 81), // Rooks - S( 8,109), S( 14,120), S( 21,128), S( 23,143), S( 31,154), S( 32,160), - S( 43,165), S( 49,168), S( 59,169) }, - { S(-40,-35), S(-25,-12), S( 2, 7), S( 4, 19), S( 14, 37), S( 24, 55), // Queens - S( 25, 62), S( 40, 76), S( 43, 79), S( 47, 87), S( 54, 94), S( 56,102), - S( 60,111), S( 70,116), S( 72,118), S( 73,122), S( 75,128), S( 77,130), - S( 85,133), S( 94,136), S( 99,140), S(108,157), S(112,158), S(113,161), - S(118,174), S(119,177), S(123,191), S(128,199) } + { S(-75,-76), S(-57,-54), S( -9,-28), S( -2,-10), S( 6, 5), S( 14, 12), // Knights + S( 22, 26), S( 29, 29), S( 36, 29) }, + { S(-48,-59), S(-20,-23), S( 16, -3), S( 26, 13), S( 38, 24), S( 51, 42), // Bishops + S( 55, 54), S( 63, 57), S( 63, 65), S( 68, 73), S( 81, 78), S( 81, 86), + S( 91, 88), S( 98, 97) }, + { S(-60,-77), S(-26,-20), S(-11, 27), S( -6, 57), S( -3, 69), S( -1, 82), // Rooks + S( 10,109), S( 16,121), S( 24,131), S( 25,143), S( 32,155), S( 32,163), + S( 43,167), S( 48,171), S( 56,173) }, + { S(-39,-36), S(-21,-15), S( 3, 8), S( 3, 18), S( 14, 34), S( 22, 54), // Queens + S( 28, 61), S( 41, 73), S( 43, 79), S( 48, 92), S( 56, 94), S( 60,104), + S( 60,113), S( 66,120), S( 67,123), S( 70,126), S( 71,133), S( 73,136), + S( 79,140), S( 88,143), S( 88,148), S( 99,166), S(102,170), S(102,175), + S(106,184), S(109,191), S(113,206), S(116,212) } };
