Degenerate nonlinear programming with a quadratic growth condition
收藏 引用
SIAM JOURNAL ON OPTIMIZATION 2000年 第4期10卷 1116-1135页
作者: Anitescu, M Univ Pittsburgh Dept Math Pittsburgh PA 15213 USA
We show that the quadratic growth condition and the Mangasarian-Fromovitz constraint qualification (MFCQ) imply that local minima of nonlinear programs are isolated stationary points. As a result, when started suffici... 详细信息
