Definition at line 51 of file BonHeuristicDive.hpp.

solution()

virtual int Bonmin::HeuristicDive::solution ( double & solutionValue, double * betterSolution )

virtual

Performs heuristic.

setInternalVariables()

virtual void Bonmin::HeuristicDive::setInternalVariables ( TMINLP2TNLP * minlp )

pure virtual

sets internal variables

Implemented in Bonmin::HeuristicDiveFractional, and Bonmin::HeuristicDiveVectorLength.
