Detailed Description

C++ wrapper for Benders' decomposition cut.

This class defines the interface for the Benders' decomposition cuts implemented in C++. Note that there is a pure virtual function (this must be implemented). This function is: benderscut_exec().

◆ SCIP_DECL_BENDERSCUTEXITSOL()

virtual scip::ObjBenderscut::SCIP_DECL_BENDERSCUTEXITSOL ( scip_exitsol )

inlinevirtual

solving process deinitialization method of Benders' decomposition cuts (called before branch and bound process data is freed)

This method is called before the branch and bound process is freed. The Benders' decomposition cuts should use this call to clean up its branch and bound data.
