In this paper, stability of soil foundation is simulated by means of analytical limit analysis in which generalized viscoplasticity is introduced by augmented Lagrangian technique.
Second, tensor completion is formulated as a convex optimization problem. A closed form for augmented Lagrangian function is obtained via relaxation technique and separation of variables technique.
其次,把张量补全作为一个凸优化问题建模,利用松弛技术和变量分离技术得到闭合的增强拉格朗日函数;
The quasi-Newton method was applied to solving the augmented Lagrangian function of nonlinear programming problems. Further, the quasi-Newton formula was given.
