Method of Centers for Multi-objective Optimization of Structures

  • 大连理工大学工业装备结构分析国家重点实验室,116023

    Graphical Abstract
    • Abstract
  • This paper presents an efficient algorithm for multi-objective optimization of large-scale structures， which is a direct extension of the method of centers for solving general nonlinear programming. At each iteration, we define a 'moving target' for each objective function, to convert it to a level constraint and then the algorithm calculates the center of the intersection of level constraints and original constraints. Some examples are given to illustrate the proposed algorithm.
