Detailed Description

Stores necessary information about the computation status of a level.

This is necessary for adaptive level generation.

Constructor & Destructor Documentation

◆ LevelInfo() [1/2]

sgpp::combigrid::LevelInfo::LevelInfo	(	size_t	numPredecessors,
		size_t	maxNewPoints,
		size_t	numPoints
	)

inlineexplicit

Creates a new level in its earliest stage.

This means that it is not ready for computation yet.

◆ LevelInfo() [2/2]

sgpp::combigrid::LevelInfo::LevelInfo	(	double	norm,
		size_t	maxNewPoints,
		size_t	numPoints
	)

inlineexplicit

Creates a new level in its latest stage, where everything has already been computed.

Member Function Documentation

◆ setPriority()

void sgpp::combigrid::LevelInfo::setPriority	(	MultiIndexQueue &	queue,
		double	priority
	)

inline

Updates the priority of this level in the priority queue.

References sgpp::combigrid::QueueEntry::priority, and sgpp::combigrid::BinaryHeap< T, Comparator >::update().

Member Data Documentation

◆ computationStage

ComputationStage sgpp::combigrid::LevelInfo::computationStage

The stage of computation of this level.

◆ handle

std::shared_ptr<MultiIndexQueue::handle_type> sgpp::combigrid::LevelInfo::handle

Handle to the queue entry if there is any.

Via this handle, the QueueEntry can be retrieved and its priority can be updated.

◆ maxNewPoints

size_t sgpp::combigrid::LevelInfo::maxNewPoints

Number of new function evaluations (grid points) that have to be done to add this level.

◆ norm

double sgpp::combigrid::LevelInfo::norm

Norm of the difference (Delta) of this level (if already computed, zero otherwise).

Referenced by python.uq.dists.MultivariateNormal.MultivariateNormal::pdf().

◆ numNotCompletedPredecessors

size_t sgpp::combigrid::LevelInfo::numNotCompletedPredecessors

Number of predecessor levels which are not in status ComputationStage::COMPLETED.

◆ numNotStartedPredecessors

size_t sgpp::combigrid::LevelInfo::numNotStartedPredecessors

Number of predecessor levels which are in status ComputationStage::NOT_STARTED.

If this is > 0, then the computation for this level may not be started (to avoid evaluating the function multiple times at the same point).

◆ numPoints

size_t sgpp::combigrid::LevelInfo::numPoints

Number of grid points in this level.

◆ priority

double sgpp::combigrid::LevelInfo::priority

priority of the level used for adaptive refinement
