Crafty has a bunch. auto-tuning them to be better than the hand-tuned default has not happened yet although we have (mainly Anthony) beat on it mercilously. Crafty has about 120 different eval features that can be adjusted, with maybe 1/2 of them represented as large arrays of values. Easily over 1000 different values to adjust. A tough task as I said...
