scip::ObjRelax Class Reference

Detailed Description

C++ wrapper for relaxation handlers.

This class defines the interface for relaxation handlers implemented in C++. Note that there is a pure virtual function (this function has to be implemented). This function is: scip_exec().

• Instructions for implementing a relaxation handler
• Corresponding C interface
