Firstly, for the algorithm, an unconstrained optimization problem is established and solved; the edges in the undirected graph corresponding to the optimal solution could provide a search range for structure learning and reduce the search space of particle swarm algorithm; then, Bayesian network structure learning is completed in the reduced space. Therefore, the leaning efficiency of particle swarm algorithm is raised. The simulation results indicate that the proposed method is able to quickly and accurately learn the optimum Bayesian network structure., authors=WANG Chunfeng¹, LÜ Juncheng², authorsList=WANG Chunfeng;LÜJuncheng, authorCompany=1.
