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.
| 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.
