Detailed Description

Abstract interface class for continuation strategies.

AbstractStrategy defines an abstract interface for continuation strategies. This interface is used by the LOCA::Stepper to manipulate continuation groups in a consistent manner. It defines a number pure virtual methods that all continuation groups must implement.


Member Function Documentation

virtual void LOCA::MultiContinuation::AbstractStrategy::postProcessContinuationStep ( LOCA::Abstract::Iterator::StepStatus  stepStatus) [pure virtual]

Perform any postprocessing after a continuation step finishes.

The stepStatus argument indicates whether the step was successful.

Implemented in LOCA::MultiContinuation::ExtendedGroup.

virtual void LOCA::MultiContinuation::AbstractStrategy::preProcessContinuationStep ( LOCA::Abstract::Iterator::StepStatus  stepStatus) [pure virtual]

Perform any preprocessing before a continuation step starts.

The stepStatus argument indicates whether the previous step was successful.

Implemented in LOCA::MultiContinuation::ExtendedGroup.

virtual void LOCA::MultiContinuation::AbstractStrategy::setPredictorTangentDirection ( const LOCA::MultiContinuation::ExtendedVector v,
int  i 
) [pure virtual]

Sets tangent to predictor.

This is required by MF which takes the tangent space, orthogonalizes it, and then sets it back in the group.

Implemented in LOCA::MultiContinuation::ExtendedGroup.
