Then that must be a bug. I can look into it, but if you want to beat me to it, you might check out FloatVectorSpecies.

Stepping through the debugger with the following mutation parameters, I can watch DoubleVectorIndividual.gaussianMutation() as it samples from a std of 0.1 when mutation gene 0. I would have expected it to scale the std to be 0.0001 or such. > > pop.subpop.0.species.min-gene = -1.0 > pop.subpop.0.species.max-gene = 1.0 > pop.subpop.0.species.min-gene.0 = -.001 > pop.subpop.0.species.max-gene.0 = .001 > pop.subpop.0.species.mutation-type = gauss > pop.subpop.0.species.mutation-stdev = 0.1 > pop.subpop.0.species.mutation-bounded = true > pop.subpop.0.species.mutation-prob = 0.03 > > Is this an error in the documentation?
