Inclusion methods

Detailed Description

methods to include specific Benders' decomposition cut methods into SCIP

This module contains methods to include specific Benders' decomposition cut methods into SCIP.

Note

The Benders' decomposition cut methods are linked to each Benders' decomposition implementation. Thus, the default Benders' decomposition implementations automatically include the necessary Benders' decomposition cut methods. For custom Benders' decomposition implementations, you can call SCIPincludeDefaultBendersCuts() in the SCIPincludeBendersMybenders() include function.
