What This Means for Your Design

Imagine trying to shine a flashlight through a foggy window. This study shows that a smart computer program (a genetic algorithm) can figure out exactly how to shape the light *before* it hits the fog so that it comes out clearly on the other side, and it does this much faster than other methods, even when the fog is very thick and the light is dim.
