Detailed Description
Meta-iterator for closely-coupled hybrid iteration, typically involving the embedding of local search methods within global search methods.
This meta-iterator uses multiple methods in close coordination, generally using a local search minimizer repeatedly within a global minimizer (the local search minimizer refines candidate minima which are fed back to the global minimizer).
The documentation for this class was generated from the following files:
- EmbedHybridMetaIterator.hpp
- EmbedHybridMetaIterator.cpp
