Relaxation Handlers
methods and files provided by the default relaxation handlers of SCIP
A detailed description what a relaxation handler does and how to add a relaxation handler to SCIP can be found here. Note that the linear programming relaxation is not implemented via the relaxation handler plugin. Per default no relaxation handler exists in SCIP. However, there are two relaxation handlers in the Relaxator example.
