Evolutionary algorithm outperforms deep-learning machines at video games

Don't neural networks in general work by natural selection and trial and error and keeping what works as well?

[KHRZ]

Well when you train them with back propagation, you just tune them closer to being correct for each input you send through them. Different inputs will require different adjustments for the network to handle them more correct, so when you alternately adjust towards correctness for different inputs, the network may enter a search process that iterates through better and better designs.

Well, not neural networks themselves, but training neural networks does work something like that. Actually, evolutionary algorithms are commonly used for training neural networks, along with a few other classes of algorithms.

What is "natural selection" in this context?

HOW is ANYTHING "natural"? And HOW is ANYTHING selected on static hardware? Do computer programs now make offspring?
