Weapon-target assignment problem based on hybrid ACA

Weapon-target assignment problem (WTA) was described and its mathematic model was established. Ant colony algorithm (ACA) was introduced briefly; a novel and equivalence coding method to solve WTA based on ACA was proposed. Aiming at ACA´s defects, the strategy to select the next node was improved; crossover and mutation in GAs were introduced in, so the search space was opened up. The steps to realize the proposed algorithm were described in details. The simulation in MATLAB program verified the validity, efficiency and simplicity to operate.
