If we support other evolutionary algorithms ( issue 136 ) we should also let the user control the mutation rate.

Actually, according to the evolutionary strategies literature, the mutation rate should evolve with the individuals in the population. Need to look into this.

This has now been implemented in the evolution-strategies-experiments branch. Will close once it gets merged into master.
