Adaptive information feedback particle swarm robot path selecting method based on multiple subgroups and system thereof

Abstract

The invention belongs to the technical field of machine learning, and discloses an adaptive information feedback particle swarm robot path selecting method based on multiple subgroups and a system thereof. Multiple diversity unified defining manners are used for a diversity evaluation strategy, thereby evaluating group diversity from multiple angles. A multiple-subgroup dividing strategy is performed on a particle group through comprehensive analysis of adaptability and spatial angle. Presetting of subgroup number is not required. A wide area searching effect in a dynamic optimizing process can be improved. A sparse processing strategy is utilized for adjusting a distribution condition in the subgroup so that the particles in the subgroup can be far from local central particles in a certain probability, thereby executing a real-time exploration process in a local area and improving diversity level in the subgroup. The adaptive information feedback particle swarm robot path selecting method and the system thereby facilitate fine exploration for a local optimal value and wide-range searching in a global range. Through result analysis on a testing problem, the method and the system according to the invention can be effectively applied in problems of multidirectional dynamic optimization and robot global path planning and further have advantages of simple and applicable method and certain use value.
