A mate suite to test multi-pv and new engines

Post by Uri Blass » Mon Aug 06, 2018 8:51 pm

Analyzed the positions by the mate solver chest
They include all the positions of all the pieces against the following pieces in their initial position

1)king(1 position)
2)king and a pawn(8 positions)
3)king and 2 pawns(28 positions)
4)king and 3 pawns(56 positions)
5)king and a knight or bishop(4 positions)
6)king and 4 pawns that include a7,b7 when the solution is mate in not more than 8 moves

Ordered the positions based on number of nodes to see the mate.

I think that it may be good if new engines can beat chest (meaning finding all the solutions in multi-pv with smaller number of nodes)
Note that i used for chest 1024 mbytes hash and I think chest that use only one core is deterministic in the number of nodes to solve a problem

Analyzed the positions by the mate solver chest
They include all the positions of all the pieces against the following pieces in their initial position

1)king(1 position)
2)king and a pawn(8 positions)
3)king and 2 pawns(28 positions)
4)king and 3 pawns(56 positions)
5)king and a knight or bishop(4 positions)
6)king and 4 pawns that include a7,b7 when the solution is mate in not more than 8 moves

Ordered the positions based on number of nodes to see the mate.

I think that it may be good if new engines can beat chest (meaning finding all the solutions in multi-pv with smaller number of nodes)
Note that i used for chest 1024 mbytes hash and I think chest that use only one core is deterministic in the number of nodes to solve a problem
