Member Function Documentation

bool SelFitnessProportionalOp::initialize ( StateP ) [virtual]

Selection operator initialization. Must be called before individual selection.

Implements SelectionOperator.

IndividualP SelFitnessProportionalOp::select ( const std::vector< IndividualP > & ) [virtual]

Select one individual from a set.

Implements SelectionOperator.

Definition at line 23 of file SelFitnessProportionalOp.cpp.

std::vector< IndividualP > SelFitnessProportionalOp::selectMany	(	const std::vector< IndividualP > &	pool,
		uint	repeats
	)

Repeatedly select from the same pool (duplicates allowed)

Definition at line 57 of file SelFitnessProportionalOp.cpp.

void SelFitnessProportionalOp::setFitnessProportional ( ) [inline]

Set the operator to use fitness proportional selection (the default)

Definition at line 39 of file SelFitnessProportionalOp.h.

void SelFitnessProportionalOp::setInverseProportional ( ) [inline]

Set the operator to use inverse fitness (badness) proportional selection

Definition at line 33 of file SelFitnessProportionalOp.h.

bool SelFitnessProportionalOp::setSelPressure ( double selPressure )

Set selection pressure value
