On Optimization Algorithms for Multi-UAVs Search Task

Since Unmanned Aerial Vehicle (UAV) swarm emerged with the merit of high efficiency, flexibility and robustness in search tasks, related research has sprung up in recent years. However, unknown target locations make swarm search a complex mission. In view of this, many optimization algorithms based on UAV swarm have been proposed and improved, which are reviewed and partitioned into non-intelligent algorithms and intelligent ones in this paper. Furthermore, the latter is subdivided into algorithm improvement and algorithm fusion, both of which are set forth at length. At the end of this paper, we analyse the existing challenges and give some insight into the future.
