Detailed Description

QPDProcessor is a derived class of NodeProcessor. It is meant to solve QPs at each node. Sometimes it also solves NLPs.

Member Function Documentation

foundNewSolution()

bool QPDProcessor::foundNewSolution ( )

virtual

True if the node processor found at least one feasible solution while processing this node.

Implements Minotaur::NodeProcessor.

getBranches()

Branches QPDProcessor::getBranches ( )

virtual

Find branches that will be used to branch at this node.

Implements Minotaur::NodeProcessor.

getWarmStart()

WarmStartPtr QPDProcessor::getWarmStart ( )

virtual

Return the warm start information that will be used to start processing children.

Implements Minotaur::NodeProcessor.

process()

void QPDProcessor::process ( NodePtr  node, RelaxationPtr  rel, SolutionPoolPtr  s_pool  )

virtual

Process relaxation at the given node. If a solution is found, it must be added to the solution pool.

Implements Minotaur::NodeProcessor.

processRootNode()

void QPDProcessor::processRootNode ( NodePtr  node, RelaxationPtr  rel, SolutionPoolPtr  s_pool  )

virtual

Process the root node.

Reimplemented from Minotaur::NodeProcessor.

writeStats() [1/2]

void Minotaur::QPDProcessor::writeStats ( ) const

inlinevirtual

Write statistics to our own logger.

Reimplemented from Minotaur::NodeProcessor.

writeStats() [2/2]

void QPDProcessor::writeStats ( std::ostream &  ) const

virtual

Write statistics to a given output stream.

Reimplemented from Minotaur::NodeProcessor.
