Member Function Documentation

select()

template<ProgramType T>

vector< size_t > Brush::Sel::SelectionOperator< T >::select ( Population< T > & pop, int island, const Parameters & p )

virtual

Selects individuals from the population based on the selection operator's strategy.

Parameters

pop	The population from which to select individuals.
island	The index of the island in a parallel genetic algorithm.
p	The parameters for the selection operator.

Returns

A vector of indices representing the selected individuals.

Reimplemented in Brush::Sel::Lexicase< T >, and Brush::Sel::NSGA2< T >.

Definition at line 13 of file selection_operator.cpp.

survive()

template<ProgramType T>

vector< size_t > Brush::Sel::SelectionOperator< T >::survive ( Population< T > & pop, int island, const Parameters & p )

virtual

Applies the selection operator to determine which individuals survive in the population.

Parameters

pop	The population in which to apply the survival selection.
island	The index of the island in a parallel genetic algorithm.
p	The parameters for the selection operator.

Returns

A vector of indices representing the surviving individuals.

Reimplemented in Brush::Sel::Lexicase< T >, and Brush::Sel::NSGA2< T >.
