# Genetic or evolutionary algorithms for filter design?

For what types of filter design problems might genetic or evolutionary algorithms be useful?

What kinds of genetic or evolutionary algorithms are used for DSP problems?

Edit: I expanded the question to include the larger set of evolutionary algorithms, such as differential evolution.

• What types of problems are genetic algorithms used for in general? Seems like they're used for optimizing systems with so many variables that they can't be optimized analytically? – endolith Dec 2 '11 at 21:44

Optimizing the design of IIR filter via genetic algorithm: Used a GA to determine the parameters for an IIR based on $H_2$ and $H_{\infty}$ criteria.
