Evolution Inside a Computer

NASA evolved an antenna that no engineer would have designed

NASA let a computer breed an antenna instead of designing one, and it came out looking like a bent paperclip. Did it work?

You'll find out

  • How you breed a solution
  • Why random changes help
  • How evolution cheats the test

Why it matters

Some problems are easier to score than to solve. Evolution turns a good score into a good design.
