	Eventually there'll be a more complicated data generation step than the one we're presently using, so having it in-lined in the loop is wasteful. Ideally also this would be update per ply and we could avoid recalculating it entirely for every query -- though it's probably ``fast enough'' for now. Also, caching is WIP.
2 days	Rename ct_k -> ct, IANAL but ...	tslil

2 days	Just some #weightgoals ;)	tslil clingman
	It turns out that while i was training on a 0/1 classification problem, i was using 2*eval - 1. Training using this function instead, and on bot-dominated game choices (chosen_player in extract.sh) seems to have given a better evaluation function. At the least, Morten's swindle doesn't work anymore.
2 days	Added license information!	tslil clingman

2 days	Finally fixed memory order of weights!	tslil clingman

2 days	New weights from a wider training	tslil clingman

2 days	Went back up to 1986 weights	tslil

2 days	There was a bug in the minimax!	tslil

2 days	Better trained weights, an important oversight in minimax (steps <=)	tslil
	I still can't tell whether if ((ply & 1) == 0) this = this - 1.0; is correct.
2 days	Seems tolerable, but not great. Still wont win or lose ???	tslil

2 days	Fixed minimax (!), fixed bugs in tak.c	tslil
	With minimax of depth 1 the evaluation function seems alright with the current method of training and generating weights
2 days	Trying minimax	tslil
