Generators for search spaces.

Function Documentation

calculateRelevantCsfs()

std::set< double > autopas::SearchSpaceGenerators::calculateRelevantCsfs	(	const NumberInterval< double > &	numberInterval,
		double	interactionLength,
		double	domainLengthX
	)

For a given domain parametrization, calculate which cell size factors (csf) in an interval actually are useful to generate distinct numbers of cells.

A cell is assumed to be of side length interactionLength * csf.

Parameters

numberInterval
interactionLength
domainLengthX	Only consider the domain length in one dimension, since the csf is also one dimensional.

Returns

Set of cell size factors that yield different numbers of cells.

cartesianProduct()

std::set< Configuration > autopas::SearchSpaceGenerators::cartesianProduct	(	const std::set< ContainerOption > &	allowedContainerOptions,
		const std::set< TraversalOption > &	allowedTraversalOptions,
		const std::set< LoadEstimatorOption > &	allowedLoadEstimatorOptions,
		const std::set< DataLayoutOption > &	allowedDataLayoutOptions,
		const std::set< Newton3Option > &	allowedNewton3Options,
		const NumberSet< double > *	allowedCellSizeFactors,
		const InteractionTypeOption &	interactionType
	)

Fills the search space with the cartesian product of the given options (minus invalid combinations).

In other words, generate every valid combination of the given options.

Parameters

allowedContainerOptions
allowedTraversalOptions
allowedLoadEstimatorOptions
allowedDataLayoutOptions
allowedNewton3Options
allowedCellSizeFactors
interactionType

Returns

A set containing all valid configurations.

inferOptionDimensions()

SearchSpaceGenerators::OptionSpace autopas::SearchSpaceGenerators::inferOptionDimensions

(

const std::set< Configuration > &

searchSet

)

Crudely trying to reconstruct the dimensions of the search space from a given set of options.

Note

It is assumed that searchSet is a complete cartesian product of all contained options.

Parameters

searchSet

Returns
