Minesweeper

Yesterday I wrote a little program to play Minesweeper so I could graph what the likelihood of winning was given certain bomb densities.

Over 19,000 games:



(The X axis is bomb density, Y is winning percentage)

Currently the AI only flags bombs based on O(n) algorithms. I don't do any hypothetical-true-leads-to-inconsistent-state eliminations which get into exponential time, though I'll probably add that sometime.

Of course, sometimes it's just a 50/50 chance and no logic will help.
