2010-11-17 05:29:10 UTC my code(no 'end')
by William Song 		I just delete the 'end' in solver.m
by William Song
2010-11-17 05:16:00 UTC my code(modified)
by William Song 		it is a tiny error. the 'end' is at wrong place.

by William Song 		apply Q-learning to find the best way. if it is not found, please make the learning-times larger.
