This is a simulation of a chemotaxis-like system which tries to solve a maze by gobbling up all the food as it goes. There is a source of food at the edge of the maze, and some initial (but slowly decaying) food spread throughout the maze. Will the population make it to the end? Can a web-based PDE solver help complete such puzzles?
