Random Thought on AI:  in hw1.q2, breadth-first search the maze will number the square in a layer by layer manner (basically kilikala~~ everywhere): imagining a little robot traveling in the maze in such manner and saying to itself: DID I NOT JUST COME BY THIS WAY! Ed agrees. 

random thought on C++: no wonder I use to get so many segmentation fault, that is what you get when you play with "fire" (null pointers).

Note to self: stop OCD yourself over missing slides of system class, just read the damn K map and jump into most recent readings of AI. catch up the slides of optimization and early readings later.
