| Abstract: |
| Surrogate based algorithms have been applied increasingly in the field of structural optimization.Compared with traditional optimization algorithms,surrogate based algorithms have advantages in dealing with the problems which have noise or are very time-consuming in simulation.To avoid falling into local optima,surrogate based algorithms use infill criteria to balance exploitation and exploration.This paper presents a new global optimization algorithm based on Multi-start local search with geometrical exploration (MSG),and compares it with efficient global optimization (EGO) by using several numerical problems.This paper analyzes the effects for MSG parameters and discusses the behaviors and applications for MSG and EGO. |
