Hybrid Biogeography-Based Optimization Algorithms

In the previous chapters, we introduce how to improve the basic BBO algorithm by using local topologies and developing new migration operators. Besides improving the intrinsic structure and operators of the algorithm, another way to improve the algorithm is combining it with other heuristic algorithms. Based on its distinctive migration mechanisms, BBO has a good local exploitation ability (Simon, IEEE Trans. Evol. Comput. 12:702–713, 2008, [10]), but its global exploration ability is relatively poor. Thus, those hybrid BBO algorithms often introduce effective global exploration mechanisms of other heuristic algorithms, so as to better balance the global and local search. This chapter describes some typical hybrid BBO algorithms.
