ctak - An implementation of Tak and a computer opponent in C

Age	Commit message (Collapse)	Author
3 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.
3 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.
3 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.
3 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.
3 days	Purged uninteresting statistics	tslil

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

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

3 days	Small changes to build ct1986	tslil clingman

3 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
