Specification
Alias: approx_method_pointer
Arguments: STRING
Description
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.
