MateFinder 9

Post by jhellis3 » Mon Feb 12, 2018 5:57 pm

I have released MateFinder 9 here:
https://github.com/jhellis3/Stockfish/releases/tag/MF_9

Bench is 6898833.

It includes the recently merged dynamic contempt, however, I have made this user selectable via UCI checkbox and the default is set to off.

Additionally, the default contempt is set to 0. If one wants to emulate current SF behavior, they will need to set contempt to 18, and check "Dynamic Contempt" in the UCI settings.

I have also provided some very basic builds. However, please note these will not be fast at all. If you want to use MateFinder for competitive purposes I highly recommend compiling it yourself.

I will also be happy to host high-performance builds should anyone desire to provide them.

Just tried it on a collection of mates and it did quite well.
Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

When testing mates from Chest database I found slightly surprising thing. Matefinder (2017) was clearly best, when solving mates for 11-20 movers. When solving 6-10 movers SF9 and Houdini6(tactical!) were equal or even faster. I have no clue why? But of course 6-10 movers should be solved all even with limited time? I will test new matefinder later, when there is fast compile.

MateFinder is struggling with this one! But it's quite a hard problem. Maybe Sting or McBrain will prove more successful.

IpMan has created some higher performance complies, and I have updated the release page to include them.

https://github.com/jhellis3/Stockfish/releases/tag/MF_9

Alternatively, you may find them at his site: http://www.ipmanchess.yolasite.com/compiles.php

Sting SF 9.8 returns move Rc8+ immediately. After 1 minutes (old dual core) gives a solid gain too.
