Detailed Description

Interface between Cbc and Cut Generation Library.

CbcCutGenerator is intended to provide an intelligent interface between Cbc and the cutting plane algorithms in the CGL. A CbcCutGenerator is bound to a CglCutGenerator and to an CbcModel. It contains parameters which control when and how the generateCuts method of the CglCutGenerator will be called.

The builtin decision criteria available to use when deciding whether to generate cuts are limited: every X nodes, when a solution is found, and when a subproblem is found to be infeasible. The idea is that the class will grow more intelligent with time.

Todo:
Add a pointer to function member which will allow a client to install their own decision algorithm to decide whether or not to call the CGL generateCuts method. Create a default decision method that looks at the builtin criteria.
Todo:
It strikes me as not good that generateCuts contains code specific to individual CGL algorithms. Another set of pointer to function members, so that the client can specify the cut generation method as well as pre- and post-generation methods? Taken a bit further, should this class contain a bunch of pointer to function members, one for each of the places where the cut generator might be referenced? Initialization, root node, search tree node, discovery of solution, and termination all come to mind. Initialization and termination would also be useful for instrumenting cbc.

Member Function Documentation

bool CbcCutGenerator::generateCuts ( OsiCuts cs,
int  fullScan,
OsiSolverInterface solver,
CbcNode node 
)

Generate cuts for the client model.

Evaluate the state of the client model and decide whether to generate cuts. The generated cuts are inserted into and returned in the collection of cuts cs.

If fullScan is !=0, the generator is obliged to call the CGL generateCuts routine. Otherwise, it is free to make a local decision. Negative fullScan says things like at integer solution The current implementation uses whenCutGenerator_ to decide.

The routine returns true if reoptimisation is needed (because the state of the solver interface has been modified).

If node then can find out depth

CbcCutGenerator& CbcCutGenerator::operator= ( const CbcCutGenerator rhs)

Assignment operator.

void CbcCutGenerator::refreshModel ( CbcModel model)

Set the client model.

In addition to setting the client model, refreshModel also calls the refreshSolver method of the CglCutGenerator object.

const char* CbcCutGenerator::cutGeneratorName ( ) const
inline

return name of generator

Definition at line 108 of file CbcCutGenerator.hpp.

void CbcCutGenerator::generateTuning ( FILE *  fp)

Create C++ lines to show how to tune.

void CbcCutGenerator::setHowOften ( int  value)

Set the cut generation interval.

Set the number of nodes evaluated between calls to the Cgl object's generateCuts routine.

If value is positive, cuts will always be generated at the specified interval. If value is negative, cuts will initially be generated at the specified interval, but Cbc may adjust the value depending on the success of cuts produced by this generator.

A value of -100 disables the generator, while a value of -99 means just at root.

int CbcCutGenerator::howOften ( ) const

void CbcCutGenerator::setWhatDepth ( int  value)

Set the cut generation depth.

If whenCutGenerator is positive and this is positive then this overrides. If whenCutGenerator is -1 then this is used as criterion if any cuts were generated at root node. If whenCutGenerator is anything else this is ignored.
