| 摘 要： | 对于一般的非线性规划给出一种精确增广Lagrange函数,并讨论其性质.无需假设严格互补条件成立,给出了原问题的局部极小点与增广Lagrange函数在原问题的变量空间上的局部极小的关系.进一步,在适当的假设条件下,建立了两者的全局最优解之间的关系.

| Abstract: | An exact augmented Lagrangian function for the nonlinear programming problems with equality constraints and inequality constraints is provided,and its properties is discussed.Without requiring strict complementarity condition,the relationship was established between the local minimizers of the original constrained problem and the local unconstrained minimizers of the augmented Lagrangian function on the space of the original problem variables.Furthermore,under some assumptions,the relationship of the global... |
