分裂可行性问题CQ算法中参数γ的影响
首发时间:2011-03-25
摘要:CQ算法求解分离可行性问题,仅涉及到分别向C、Q上的正交投影,这使它成为求解SFP的一个最重要的方法,但是参数γ的影响不是很清楚。这篇文章的目的是研究随着参数γ的变化怎样影响收敛时间,获得了一些结果。在文章的最后给出了一些数值试验。

On the influence of parameter γ in CQ algorithm for the split feasibility problem
Abstract:The CQ algorithm to solve the split feasibility problem(SFP), involving only the orthogonal projections onto C and Q, resepectively, which makes it the most important method for the SFP. But the influence of parameterγis always not very clear. The purpose of this paper is to study the variation of parameter γhow to affect the convergence time, obtaining some conclusions. In the last section, we give some experimental results.
Keywords: CQ algorithm parameterγ the SFP
