A genetic algorithm designed an FPGA logic that couldn't possible work under usual rules, but actually did and used less resources than any human design. As it turned out, the genetic algorithm exploited some analogue properties of the FPGA, which a human designer would never attempt to do. Genetics seem to favor efficient systems over understandable and easily extendable systems. Paper "Adrian Thompson, An Evolved Circuit, Intrinsic in Silicon, Entwined With Physics."
