As I worked through this lab and the video, I became more aware of
the thought process that goes into tic-tac-toe. However, it was not
until I saw all the reward possibilities for the initial state of the
board, and then made the computer play itself that I appreciated how
complex the game is and how many possibilities there are on a relatively
simple board. I am also wondering when the computer plays itself,
does the game always end in a tie? I suppose I could write a program for
this that plays the game a set number of times and makes a list of the
outcomes and then counts the wins, losses, and ties for a particular
player.
