Abstract: A hybrid optimazation approach which is combined the Artificial Fish School Algorithm（AFSA） with the improving Optimization Approach on using Fishing Strategy（FSOA） is presented in this paper.The main idea of this hybrid optimization method is that AFSA and improving FSOA are used alternating in the sequence of operations for searching the global optimal solution，that AFSA is used to find the local optimal domain and improving FSOA is made use of improving the accurate numerical solution and accelerating the convergence rate.It shows from the optimization experimental results that the optimization approach has the performances of rapid convergence rate，high accurate numerical solution，robust in solving global optimal solution，and good stability.So the optimization algorithm is effective and feasible in solving high dimension and complex function’ optimization problems.
