In this paper we prove a descent property of implicit method for monotone variatonal inequality in , give a further discussion to the implicit method under G norm and draw some similar conclusions.
In this paper, a new self-adapt projection contraction method solving the quadratic programming is established. We give a self-adapt rule for parameter .The solution of the problem is obtained after steady changing pa...
本文考虑如何求解下面的l_1-模问题 min sum from i=1 to m(|X_i|) s.t Ax=a (1.1) Bx=b 其中a.b∈R^n为已知向量,A.B是m×n实矩阵且满足A+iB=JF,J^T=(e_i_1),…,e_i_m)是单位矩陈的列子矩阵,F=(f_(jk))是一个n×n的离散Fourier系数矩阵。
