Multiple UCAVs mission assignment based on modified Gravitational Search

With further developments of Uninhabited Combat Aerial Vehicles (UCAVs), the problem of multiple UCAVs mission assignment is a hot point, and many solutions aimed at multiple UCAVs mission assignment are proposed in the past years. However, it's still difficult to satisfy the actual need of complicated battlefield owing to the larger scale of problems and the limit of operation speed. In this paper, we proposed a novel solution for UCAVs mission assignment based on a modified Gravitational Search Algorithm (GSA). The basic GSA is modified by improving the initialization, the mass weighing value and natural selection rules are also adopted. Comparative experimental results verified that the three parts of the GSA can be improved: algorithmic reconnaissance ability, speed and optimization of finding the solution. The results show that our proposed GSA can solve the multiple UCAVs mission assignment effectively.
