In 1963, a couple of students were working in a wind-tunnel, attempting to find a way to figure out how to design surfaces to produce a given airflow. That was, and still is, a difficult problem. There are no simple formula. They decided to see if they could use the power of evolution to solve the problem, and it worked.
Here’s a link to the relevant section of “A Hitchhiker’s guide to Evolutionary Computation.”
I mentioned evolutionary programming in this episode, but don’t provide much detail. For those who are interested, here’s a link that provides an introduction to the topic.
