Hybrid strategies

Here: optimization procedures, which combine an EA with mostly problem-specific search algorithms. As a general rule, the problem specific search algorithm determines or approximates the local optima (see local search) and the EA operates on the set of local optima. Additional variants of hybrid EA are characterized by using problem-specific procedures for the initialization of the start population and/or local search procedures for ``post-optimization'' of the EA results.
