Detailed Description

template<typename GeneType = double>
class galib::benchmark::SphereFunction< GeneType >

Implementation of the Sphere function.

A simple unimodal function representing an n-dimensional paraboloid. Global minimum: f(0, ..., 0) = 0.

Template Parameters

GeneType

The numeric type of the genes.

Member Function Documentation

evaluate()

template<typename GeneType = double>

double galib::benchmark::SphereFunction< GeneType >::evaluate ( const std::vector< GeneType > &  phenotype ) const

inlineoverridevirtual

Evaluates the N-dimensional Sphere function.

Parameters

phenotype

Input vector.

Returns

Fitness value.

Implements galib::FitnessFunction< GeneType >.

Definition at line 48 of file SphereFunction.h.

getLowerBound()

template<typename GeneType = double>

GeneType galib::benchmark::SphereFunction< GeneType >::getLowerBound ( std::size_t  dimension ) const

inlineoverridevirtual

Gets the lower bound for a specific dimension.

Parameters

dimension

Index of the dimension.

Returns

Lower bound value.

Implements galib::FitnessFunction< GeneType >.

Definition at line 59 of file SphereFunction.h.

getUpperBound()

template<typename GeneType = double>

GeneType galib::benchmark::SphereFunction< GeneType >::getUpperBound ( std::size_t  dimension ) const

inlineoverridevirtual

Gets the upper bound for a specific dimension.

Parameters

dimension

Index of the dimension.

Returns

Upper bound value.

Implements galib::FitnessFunction< GeneType >.

Definition at line 60 of file SphereFunction.h.

name()

template<typename GeneType = double>

std::string galib::benchmark::SphereFunction< GeneType >::name ( ) const

inlineoverridevirtual

Short identifier used to select a GPU evaluation kernel.

Override in benchmark subclasses to enable GPU-side evaluation ("Sphere", "Rastrigin", "HeavyTrig"). Return empty string (default) to use the CPU callback path.

Returns

Problem name string, or "" for custom functions.

Reimplemented from galib::FitnessFunction< GeneType >.

Definition at line 57 of file SphereFunction.h.

size()

template<typename GeneType = double>

std::size_t galib::benchmark::SphereFunction< GeneType >::size ( ) const

inlineoverridevirtual

Returns the dimensionality of the optimization problem.

Returns

Number of dimensions.

Implements galib::FitnessFunction< GeneType >.
