A Hierarchical Particle Swarm Optimization for Solving Bilevel Programming Problems

  title={A Hierarchical Particle Swarm Optimization for Solving Bilevel Programming Problems},
  author={Xiangyong Li and Peng Tian and Xiaoping Min},
The bilevel programming problem (BLPP) has proved to be a NP-hard problem. In this paper, we propose a hierarchial particle swarm optimization (PSO) for solving general BLPPs. Unlike most traditional algorithms designed for specific versions or based on specific assumptions, the proposed method is a hierarchical algorithm framework, which solves the general bilevel programming problems directly by simulating the decision process of bilevel programming. The solving general BLPPs is transformed… CONTINUE READING
