A Multi-Strategy Improved Artemisinin Algorithm For UAV 3-D Path Planning

As the application of drones becomes increasingly widespread, path planning for drones in various complex environments has gradually emerged as a challenge. It involves searching for a path that is both short and safe. Traditional path-planning methods perform well in simple environments, but they fall short in complex scenarios. A smooth obstacle-avoidance path planning scheme is proposed for UAVs based on a 3D Halton-Cauchy Diffusion Artemisinin Optimization (CDAO) algorithm. The approach enhances initial solution quality through 3D Halton sequence initialization, thereby enhancing convergence accuracy and speed by integrating a Cauchy elite population genetic strategy and a diffusion thinking strategy. The effectiveness of the CDAO algorithm is validated in three environments with varying complexity levels. Comparative experiments demonstrate that CDAO outperforms other swarm intelligence optimization algorithms such as PSO, HLOA, PO, and SCA in adaptability and optimization performance.
