2 days	Corrected generation of training data for 6s	tslil clingman

2 days	Don't generate header for training data + tweaks	tslil
	For some reason it would seem that moving flats to a lower value and increasing the proximity between caps and top flats improves acquisition. Still not great, but every bit counts.
2 days	Change the training data generation a little	tslil clingman
	Although it pains me to say it, ``label smoothing'' appears to be actually work. I'm also currently experimenting with training simply against _all_ games, instead of only bot matches. Once the training finishes i'll pit cttei against itself with old and new weights, hopefully there'll be a noticeable improvement.
2 days	Rename ct_k -> ct, IANAL but ...	tslil

2 days	Small typo in generated output for weights	tslil clingman

2 days	Correct line clearing behaviour, EXIT_FAILURE <~ -1	tslil clingman

2 days	Renamed binaries	tslil clingman

2 days	TEI interface working!	tslil clingman

2 days	Tried some naive iterative deepening. Work on TEI interface next	tslil clingman
	If TEI is implemented, then i could make use of Morten's racetrack (https://github.com/MortenLohne/racetrack) and develop a quantitative measure of the bot's performance. This is the current priority.
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	Fairly important bug fixes to lcdlib, LCD now echoes input!	tslil clingman
	Input polling without line-buffering is done using ncurses, so the buildroot configuration had to change accordingly to include that library. The Makefile changed to accommodate stand-alone building of ct1986 and to include -lcurses where appropriate. There were also some typos about copying ct1986 and ctaklm to the correct directories.
2 days	Try to squeeze out a little more performance	tslil clingman
	``Common wisdom'' dictates that placements are often better than stack moves, so we bias the generated move list in this fashion. Seems to be a little faster.
2 days	Purged uninteresting statistics	tslil

2 days	Syntax errors, small tweak to training data generation	tslil clingman

2 days	Cleaned up build system	tslil clingman

2 days	Skeleton readme	tslil clingman

2 days	Added license information!	tslil clingman

2 days	Print progress before recursion rather than after	tslil clingman

2 days	Typo	tslil clingman

2 days	Merge branch 'zobrist'	tslil clingman

2 days	Small oversight	tslil clingman

2 days	Removed treap in favour of linked-list chained hash table	tslil clingman

2 days	Small changes to build ct1986	tslil clingman

2 days	It would appear that any function call whatsoever is slower :/	tslil clingman
	For now we'll stay with directly recomputing it at each non-terminal node
2 days	Storing best moves!	tslil clingman

2 days	I don't have the presence of mind to debug this right now	tslil clingman

2 days	This matches alpha-beta!	tslil clingman

2 days	Somehting along these lines, i'm tired	tslil clingman

2 days	Stable negamax-alpha-beta fail-soft	tslil clingman

2 days	Small oversight	tslil clingman

2 days	Once again, adding TT changes the outcome	tslil clingman

2 days	Actually it seems before i was mis-counting	tslil clingman

2 days	There is still a bug, it doesn't appear to be checking enough	tslil clingman

2 days	Stripping debug stuff	tslil clingman

2 days	It was a silly typo! Hoorah!	tslil clingman

2 days	Still bugs...	tslil clingman

2 days	Still some bugs, standing stone becomes flat at depth4 self-play??	tslil clingman

2 days	There's still something wrong	tslil clingman

2 days	Incidental bugfix	tslil clingman

2 days	This looks better to me and confirms scribbles on paper	tslil clingman

2 days	I don't understand why action_list.c:306 != 259	tslil clingman

2 days	There are still some bugs in the undo almost surely...	tslil clingman

2 days	Lots of bugfixes, mostly uint vs int. Still weirdness in game	tslil clingman

2 days	Memory leak fix	tslil clingman

2 days	This is the basic idea, there's ≥ 1 bug (generates illegals...)	tslil clingman

2 days	Working on action lists to refactor	tslil clingman

2 days	Still trying	tslil clingman
