Abstract:

To solve the problems of the slow convergence rate and the low search efficiency in solving weapon-target assignment (WTA), an improved differential evolution (DE) algorithm is proposed. Firstly, the WTA model is established under the multi-constraint condition, and the dynamic WTA (DWTA) problem is discretized into the static WTA (SWTA) problem. Secondly, the exploration and exploitation capabilities of DE algorithm gorithm are slightly balanced by the random neighborhood-based mutation strategy, and the adaptive parameter setting method based on historical archive is adopted to dynamically update parameters based on "elite" information. Finally, through the comparative experiments with five kinds of variant DE algorithms, the present algorithm is proved to have a high searching accuracy, a fast convergence speed and a strong robustness.

Key words: weapon-target assignment (WTA), differential evolution algorithm, random neighbourhood, self-adaptation parameter
