Scientists have engineered bacteria to solve the Hamilton Path Problem faster then any computer. The Hamelton problem is the problem of finding the shrotest path that visits all the “nodes” (think countries or cities) and only visit a node once. The bacteria was able to solve the problem quickly because each cell solved one part of the problem in parallel with the other cells in the colony. The problem was represented in the bacterias DNA which was randomly combined with the DNA of the other bacteria. The bacteria that found a solution would glow yellow. The paper can be found here.
