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

getIndMutProb()

double Mutation::getIndMutProb

(

)

Return current individual mutation probability.

Definition at line 10 of file Mutation.cpp.

initialize()

bool Mutation::initialize

(

StateP

state

)

Initialize all mutation operators of all active genotypes.

Definition at line 45 of file Mutation.cpp.

mutate()

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.

mutation()

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

Definition at line 133 of file Mutation.cpp.

registerParameters()

void Mutation::registerParameters

(

StateP

state

)

Register mutation related but Genotype unrelated parameters.

Definition at line 30 of file Mutation.cpp.

setIndMutProb()

double Mutation::setIndMutProb

(

double

newProb

)

Set new individual mutation probability (ignored if not [0, 1])

Definition at line 19 of file Mutation.cpp.
