MetaBoosting: Enhancing Integer Programming Techniques by Metaheuristics, optimization methods for solving hard combinatorial problems rely at some point on tree search. Applying more effective metaheuristics for obtaining better heuristic solutions and thus tighter bounds in order to prune the search tree in stronger ways is the most obvious possibility.

Decomposition Techniques as Metaheuristic Frameworks,or solution methods. Moreover a long-established research literature uses them for defining problem-specific heuristics. More recently it has been observed that they can be the basis also for designing metaheuristics.
