This should be called from the SCIPincludeBendersXyz for the associated Benders' decomposition. It is only possible to include a Benders' cut algorithm if a Benders' decomposition has already been included This should be done during the problem creation stage.

Returns: SCIP_OKAY is returned if everything worked. Otherwise a suitable error code is passed. See SCIP_RETCODE for a complete list of error codes.

Precondition

This method can be called if SCIP is in one of the following stages:

Note: method has all Benders' decomposition callbacks as arguments and is thus changed every time a new callback is added in future releases; consider using SCIPincludeBendersBasic() and setter functions if you seek for a method which is less likely to change in future releases

benders	Benders' decomposition
name	name of Benders' decomposition cuts
desc	description of Benders' decomposition cuts
priority	priority of the Benders' decomposition cuts
