Detailed Description

C++ wrapper for propagators.

This class defines the interface for propagators 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 propagator
• List of available propagators
• Corresponding C interface
