| Abstract: | Based on projection index function,projection pursuit cluster analyis is a process to analyze optimization problems under certain constrain conditions.This paper employs Particle Swarm Optimization(PSO) to solve projection index function,and constructs a projection pursuit cluster model to evaluate forest carrying capacity.Simulation results show that this PSO-based model is simpler and easier to realize with less parameters,compared with GAbased model.Moreover,the proposed model can give optimal solutions ... |
