I wrote up an essay only to see it get deleted. Yay.
Some things I did:
- Add material and game length scaling, so that Patricia is motivated to keep pieces on the board and win quickly.
- Add bonuses for directly attacking the enemy king
- Add bonuses for castling opposite side
- Dial up the sacrifice bonuses, but don't scale them higher when Patricia is winning.
After talking with Stephan Pohl, who was very helpful in showing me reasons why some sacrifices weren't being counted, I tried to change the definition of "sacrifices" in Patricia to match the EAS tool's (for example, you have to go 8 plies without any captures after a sacrifice in order for it to be counted), but nothing worked, except for making it so that if it's not legal to take the "sacrificed" piece (e.g. taking advantage of pins), it doesn't count.
Even with the new net, Patricia's suffering a bit when it comes to strength, it's still only about 3000. But I easily have a couple hundred ELO in search left, and the EAS score is now release worthy.
