Abstract: Adaptive krill herd algorithm is proposed on the basis of the basic krill herd algorithm, by establishing genetic breeding mechanism and adding an adaptive link which is made of genetic and optimization operators. This new algorithm not only improves the global optimization performance, but also obtains robust result with good quality. The method employing adaptive evolutionary krill herd algorithm to simultaneously optimize the initial weights and thresholds of the Elman neural network is presented. And on the basis of it, a target threat assessment model is established to seek global excellent result. Through simulation and analysis of experimental data, the feasibility and efficiency of the algorithm in the application of target threat assessment are verified.
