scip::ObjPresol Class Reference

Detailed Description

C++ wrapper for presolvers.

This class defines the interface for presolvers 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 presolver
• List of available presolvers
• Corresponding C interface

Member Function Documentation

operator=() [1/2]

ObjPresol & scip::ObjPresol::operator= ( const ObjPresol &  o )

delete

assignment of polymorphic classes causes slicing and is therefore disabled.

operator=() [2/2]

ObjPresol & scip::ObjPresol::operator= ( ObjPresol &&  o )

delete

assignment of polymorphic classes causes slicing and is therefore disabled.
