We told the computer program what performance the antenna should have, and the computer simulated evolution, keeping the best antenna designs that approached what we asked for. Eventually, it zeroed in on something that met the desired specifications for the mission.

The software also may invent designs that no human designer would ever think of.

The AI software examined millions of potential antenna designs before settling on a final one. Through a process patterned after Darwin's 'survival of the fittest,' the strongest designs survive and the less capable do not.
