Pointer to sub-method to apply to a surrogate or branch-and-bound sub-problem




  • Alias: approx_method_pointer

  • Arguments: STRING


The method_pointer keyword is used to specify a pointer to an optimization or least-squares sub-method to apply in the context of what could be described as hierarchical methods. In surrogate-based methods, the sub-method is applied to the surrogate model. In the branch-and-bound method, the sub-method is applied to the relaxed sub-problems.

Any model_pointer identified in the sub-method specification is ignored. Instead, the parent method is responsible for selecting the appropriate model to use as specified by its model_pointer. In surrogate-based methods, it is a surrogate model defined using its model_pointer. In branch-and-bound methods, it is the relaxed model that is constructed internally from the original model.
