Show that it is impossible to completely cover the "mutilated-checkerboard" with 1 x 2 tiles so that the tiles neither overlap nor stick out over the edge of the board.

first solve the problems that are given. Next, make a list of the subproblems you considered while solving them. Discuss how a computer might be programmed to solve each of the given problems, and how each of the problems might be represented to the computer. If you find a state-space representation for a problem, estimate the size of the state space and try to identify heuristics and algorithms the machine could use to search it. If computer time is available to you, choose a problem and try to implement a computer program that can solve it.
