Detailed Description

Default node processor used in solver for now.

PCBProcessor is a derived class of NodeProcessor. It is meant to solve LPs at each node. It is used in a simple MILP branch-and-bound. As a stop-gap measure, it is being used for MINLP branch-and-bound as well.

Member Function Documentation

foundNewSolution()

bool PCBProcessor::foundNewSolution ( )

virtual

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

Implements Minotaur::NodeProcessor.

getBranches()

Branches PCBProcessor::getBranches ( )

virtual

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

Implements Minotaur::NodeProcessor.

getWarmStart()

WarmStartPtr PCBProcessor::getWarmStart ( )

virtual

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

Implements Minotaur::NodeProcessor.

process()

void PCBProcessor::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.

setCutManager()

void PCBProcessor::setCutManager ( CutManager *  cutman )

virtual

Reimplemented from Minotaur::NodeProcessor.

writeStats() [1/2]

void PCBProcessor::writeStats ( ) const

virtual

Write statistics to our own logger.

Reimplemented from Minotaur::NodeProcessor.

writeStats() [2/2]

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

virtual

Write statistics to a given output stream.

Reimplemented from Minotaur::NodeProcessor.
