| 摘 要： | Based on the interval analysis, an interval slope method is proposed for finding all global minimizers of a several peaks function f on domain X^0包含于R^n, which is given by interval slope discard tests and interval extension of objective function.Numerical results of representative test functions show that this method is practical and effective.

| Abstract: | Based on the interval analysis, an interval slope method is proposed for finding all global minimizers of a several peaks function f on domain Xo Rn, which is given by interval slope discard tests and interval extension of objective function. Numerical results of representative test functions show that this method is practical and effective. |
