public class BitVectorSpecies
extends VectorSpecies

BitVectorSpecies is a subclass of VectorSpecies with special constraints for boolean vectors, namely BitVectorIndividual.

BitVectorSpecies can specify some parameters globally, per-segment, and per-gene. See VectorSpecies for information on how to this works.

BitVectorSpecies provides support for two ways of mutating a gene.

• reset Replacing the gene's value with a value uniformly drawn from the gene's range [true, false].
• flipFlipping the bit of the gene value. This is the default.

BitVectorSpecies provides support for two ways of initializing a gene. The initialization procedure is determined by the choice of mutation procedure as described above. If the mutation is floating-point (reset, gauss, polynomial), then initialization will be done by resetting the gene to uniformly chosen double floating-point value between the minimum and maximum legal gene values, inclusive. If the mutation is integer (integer-reset, integer-random-walk), then initialization will be done by performing the same kind of reset, but restricting values to integers only.

Parameters

base.mutation-type or
base.segment.segment-number.mutation-type or
base.mutation-prob.gene-number reset, flip, (default=flip)	(the mutation type)

Description copied from class: Species

The default version of setup(...) loads requested pipelines and calls setup(...) on them and normalizes their probabilities. If your individual prototype might need to know special things about the species (like parameters stored in it), then when you override this setup method, you'll need to set those parameters BEFORE you call super.setup(...), because the setup(...) code in Species sets up the prototype.
