Li Liang,Chi Shichun,Lin Gao

Strategic Study of CAE 2005, Volume 7, Issue 4, Pages 64-68

Abstract:

Maximum entropy principle is imported into the basic complex method in order to improve the ratiopresented as follows: firstly the search optimum design point is defined as the design point whose entropyThe basic complex method and the complex method based on maximum entropy principle are used to locatesoil slopes and the comparisons of the results suggest that the ability of the complex method based on maximumentropy principle to find global optimum is stronger than that of the basic complex method.
