Impression of Week 9

      We did some test on Minimax.
      We were given three SubtractSquareState and we wanted to know what outcome of our Minimax meant our function was more likely to be correct. For states with current value 9, 10 and 11, the outcomes are all win or all lose. From that we cannot conclude whether our Minimax is working or not, so we would want a state with less wins to test our code on. In the unit test for Minimax, Danny used a state whose current value is 25 and this state has only one move to win. If that winning move is returned, which is nearly impossible for a random strategy, our Minimax is very likely to be correct.
      Later in that week, we saw some other functions.

      N = 5
      M = 2

      def f(N):
          return M * g(N + 1)

      def g(N):
          return M * N

      def h(N):
          return f(g(N))

      What we learned from them was when the name of a variable is used more than one time, which one should we refer to. The rule is the nearest one is what we need.
