Over decades of use in diverse scientific and engineering fields, evolutionary optimization has acquired a reputation for being a kind of universal acid—a general purpose approach that routinely procures useful solutions to optimization problems with rugged, dynamic, and noisy cost functions over search spaces consisting of strings, vectors, trees, and instances of other kinds of data structures. Remarkably, despite years of research, the means by which evolutionary algorithms work is not well understood.
The
generative fixation hypothesis is a novel account of optimization in genetic algorithms. This hypothesis proceeds from evidence that genetic algorithms with uniform crossover can implement a generalpurpose,
noisetolerant global optimization heuristic, called hyperclimbing,
extraordinarily efficiently. The generative fixation
hypothesis departs from the reigning hypothesis in genetic algorithmics—the building block hypothesis—at a
fundamental level.
