Abstract

In this paper, an algorithm named Quantum and Biogeography based Optimization(QBO) is proposed to investigate the possibility of optimization by evolving multiple Quantum Probability Models(QPMs) via evolutionary strategies inspired by the mathematics of biogeography. In QBO, each QPM modeling an area in decision space represents a habitat, the whole population of QPMs evolve as an ecosystem with multiple habitats interacting. The migration and immigration mechanisms originally presented in Biogeography Based Optimization (BBO) [1] is introduced into QBO to implement the efficient information sharing among QPMs, which enhance the evolution of probability models towards the better status that can generate more better solutions. Experimental results on classical 0/1 knapsack problems of various scale show that the mechanisms in BBO are feasible to evolve multiple QPMs, and QBO is efficient for hard optimization problem.
