Detailed Description

Extend this class with model specific logic, and register through MPSolver::SetCallback, passing a pointer to this object.

Constructor & Destructor Documentation

MPCallback()

operations_research::MPCallback::MPCallback ( bool might_add_cuts, bool might_add_lazy_constraints )

inline

If you intend to call call MPCallbackContext::AddCut(), you must set might_add_cuts below to be true. Likewise for MPCallbackContext::AddLazyConstraint() and might_add_lazy_constraints.

Member Function Documentation

might_add_cuts()

bool operations_research::MPCallback::might_add_cuts ( ) const

inline

Definition at line 153 of file linear_solver_callback.h.

might_add_lazy_constraints()

bool operations_research::MPCallback::might_add_lazy_constraints ( ) const

Definition at line 154 of file linear_solver_callback.h.

RunCallback()

virtual void operations_research::MPCallback::RunCallback ( MPCallbackContext * callback_context )

pure virtual

Threading behavior may be solver dependent:

• Gurobi: RunCallback always runs on the same thread that you called MPSolver::Solve() on, even when Gurobi uses multiple threads.

Implemented in operations_research::MPCallbackList.
