After the last posting on David Goldberg’s lab, I note another genetic algorithms oriented blog in the Genetic Argonaut by Marcelo di Brito. The current post is on optimizing the shape of a lens. The article gives a detailed description of a nice experiment to find the best lens with a variety of genetic algorithm-based approaches. It is a good introduction to some of the newer additions to the basic genetic algorithm. I would love to see how this compares to optimization-based approaches.
