\nHappy Independence Day! To celebrate our nation’s founding, my family and I often hit up the Cape. This year was no exception, there’s little to report. The weather has been spotty: a little rain here, a few showers there, but nothing substantial. Someone was playing bagpipes the other night.

Maybe if I do, someone will be able to tell me if my results make any sense. Whether or not my programs reproduce the classical results isn’t really the point, though. Look at the evolution of strategies for playing the iterated prisoner’s dilemma<\/a>: they make perfect modern art tile mosaics! I bet someone’d love to have this pattern on their pool floor or garden wall. (Don’t be alarmed that they don’t appear all that related. Each row in black represents the fittest individual from one of a number of independent runs. That is, they probably never had the chance to meet each other.) Imagine the graphic tastefully obscured by flowering vines. (Click on it for a larger image.<\/a>)\n<\/p>\n \n \nI can see an upside-down raccoon in it.
