problem and a discretized Cahn–Hilliard equation with obstacle potential illustrate the re- liability and efficiency of the new approach. 1. Introduction We consider the iterative solution of large scale saddle point problems of the form (1.1) u ∗ ∈ R n , w ∗ ∈ R m : F B T...
Identifying and attacking the saddle point problem in high-dimensional non-convex optimization Yann N. Dauphin 许多科学和工程领域面临的一个核心挑战是最小化连续高维空间中的非凸误差函数。梯度下降或拟牛顿法几乎普遍用于执行此类最小化,人们通常认为,这些局部方法难以找到全局最小值的主要原因是局部最小值的扩...
We consider problems where D = 0 or [parallel]D[parallel] is small, so that our problems retain the character of a (generalized) saddle-point problem. In addition, certain finite element stabilization schemes yield B [not equal to] C [1, 22] and [24, Sections 7.5 and 9.4], while ...

Saddle point problems arise from many wireless applications, and primal-dual iterative algorithms are widely applied to find the saddle points. In the existing literature, the convergence results of such algorithms are established assuming the problem specific parameters remain unchanged during the iteratio...
We first consider in Section II.1.1 the simple case of a saddle point problem corresponding to the minimization of a linearly constrained quadratic functional. This case is extended in Section II.1.2 to a more general case. The matter of approximating the solution will then be considered under ...
