Some relaxed hybrid iterative schemes for approximating a common element of the sets of zeros of infinite maximal monotone operators and the sets of fixed points of infinite weakly relatively non-expansive mappings in a real Banach space are presented. Under mild assumptions, some strong convergence theorems are proved. Compared to recent work, two new projection sets are constructed, which avoids calculating infinite projection sets for each iterative step. Some inequalities are employed sufficiently to show the convergence of the iterative sequences. A specific example is listed to test the effectiveness of the new iterative schemes, and computational experiments are conducted. From the example, we can see that although we have infinite choices to choose the iterative sequences from an interval, different choice corresponds to different rate of convergence.
提出了一些松弛的混合迭代格式,用于逼近实巴拿赫空间中无限极大单调算子的零点集与无限弱相对非扩张映射的不动点集的公共元。在温和假设下,证明了一些强收敛定理。与近期工作相比,构造了两个新的投影集,避免了在每个迭代步计算无限个投影集。充分利用了一些不等式来证明迭代序列的收敛性。列举了一个具体例子来检验新迭代格式的有效性,并进行了计算实验。从该例子可以看出,尽管我们可以从一个区间中无限次地选择迭代序列,但不同的选择对应不同的收敛速度。
