Detailed Description

Mutation class - handles mutation of _individuals_ (as opposed to MutationOp class that mutates genotypes).

Mutation class is in fact a repository of every mutation operator (MutationOp) for every active Genotype (the genotypes used in individuals). Determines which MutationOp will be used for each genotype. (every operator for every genotype has a usage probability)

Member Function Documentation

bool Mutation::mutate

(

IndividualP

ind

)

Mutate an individual.

May mutate one or more genotypes in given individual. Determines which MutationOp to use on each genotype.

Definition at line 153 of file Mutation.cpp.

uint Mutation::mutation

(

const std::vector< IndividualP > &

pool

)

Perform mutation on a pool of individuals.

Mutation probability may be defined with 2 parameters:

• (not implemented!) if geneMutProb_ is defined in config, use that parameter with genotype's genome size
• otherwise use indMutProb_

Called by: Algorithm::advanceGeneration

Returns:

number of mutated individuals
