Detailed Description

template<ProgramType T>
struct Brush::Pop::Archive< T >

The Archive struct represents a collection of individual programs.

The Archive struct is used to store individual programs in a collection. It provides functionality for initializing, updating, and sorting the archive based on complexity or objectives. The archive can be operated on by a single thread.

Template Parameters

T	The program type.

Member Function Documentation

init()

template<ProgramType T>

void Brush::Pop::Archive< T >::init

(

Population< T > &

pop

)

Initializes the archive with individuals from a population.

Parameters

pop	The population from which to initialize the archive.

sameFitComplexity()

template<ProgramType T>

bool Brush::Pop::Archive< T >::sameFitComplexity ( const Individual< T > & lhs, const Individual< T > & rhs )

static

Checks if two individuals have the same fitness complexity.

This static function is used to check if two individuals have the same fitness complexity. It is used as a comparison function for finding duplicates in the population.

Parameters

lhs	The left-hand side individual to compare.
rhs	The right-hand side individual to compare.

sameObjectives()

template<ProgramType T>

bool Brush::Pop::Archive< T >::sameObjectives ( const Individual< T > & lhs, const Individual< T > & rhs )

static

Checks if two individuals have the same objectives.

This static function is used to check if two individuals have the same objectives. It is used as a comparison function for finding duplicates in the population.

Parameters

lhs	The left-hand side individual to compare.
rhs	The right-hand side individual to compare.

Definition at line 56 of file archive.cpp.

Here is the call graph for this function:

set_objectives()

template<ProgramType T>

void Brush::Pop::Archive< T >::set_objectives

(

vector< string >

objectives

)

Sets the objectives for the archive.

This function sets the objectives for the archive. The objectives are used for sorting the archive.

Parameters

objectives

The objectives to set for the archive.

sortComplexity()

template<ProgramType T>

bool Brush::Pop::Archive< T >::sortComplexity ( const Individual< T > & lhs, const Individual< T > & rhs )

static

Sorts the population in increasing complexity.

This static function is used to sort the population in increasing complexity. It is used as a comparison function for sorting algorithms.

Parameters

lhs	The left-hand side individual to compare.
rhs	The right-hand side individual to compare.

Definition at line 17 of file archive.cpp.

Here is the call graph for this function:

sortObj1()

template<ProgramType T>

bool Brush::Pop::Archive< T >::sortObj1 ( const Individual< T > & lhs, const Individual< T > & rhs )

static

Sorts the population by the first objective.

This static function is used to sort the population by the first objective. It is used as a comparison function for sorting algorithms.

Parameters

lhs	The left-hand side individual to compare.
rhs	The right-hand side individual to compare.
