INVERSE PROBLEMS 2006年 第6期22卷 2021-2034页
作者: Xu, Hong-Kun Univ KwaZulu Natal Sch Math Sci ZA-4000 Durban South Africa
A variable Krasnosel'skii-Mann algorithm generates a sequence {x(n)} via the formula x(n+1) = (1 - alpha(n))x(n) + alpha(n)T(n)x(n), where {alpha(n)} is a sequence in [0, 1] and {T-n} is a sequence of nonexpansive... 详细信息

OPTIMIZATION 2023年 第10期72卷 2661-2678页
作者: Yao, Zhongsheng Vong, Seakweng Univ Macau Dept Math Ave Univ Macau Peoples R China
In this paper, we study two inertial-type algorithms with a relaxed splitting method for solving the split feasibility problem in Hilbert spaces. Weak convergence is established without assuming conditions such as Sig... 详细信息
