Animation showing evolution of program shape in genetic programming

Note how population spreads out. Moving to bigger and deeper programs. Buts alos not how it moves away from left hand edge of the search space, where the full trees are towards the stepped parabola indicating where the random program shapes are. Finally notice the population does not cross into the lower half of the search space.

Depth (horizontal) and size (vertical) of individual programs in a Quintic GP population every five generations. The crosswires indicate the location of the population mean and the standard deviation of depth and size. Standard subtree crossover.
