scip::ObjNodesel Class Reference

Detailed Description

C++ wrapper for primal heuristics.

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

• Instructions for implementing a node selector
• List of available node selectors
• Corresponding C interface
