In order to improve the solving performance of the original bat-inspired algorithm (BA),increase its searching efficiency,and avoid falling into local optimal solution,the neighborhood of the local optimum and the frequency interval in the original BA were optimized by using the chaos optimization method based on Fuch mapping.Furthermore,a new hybrid bat-inspired algorithm named as Fuch chaos bat-inspired algorithm (FCBA) was proposed.The numerical results show that FCBA has better convergence performance,and can converge faster to the optimal solution of numerical examples.
