分裂等式问题是分裂可行性问题的推广,同时也是多集分裂等式问题的特例。本文提出了一种迭代步长分裂自适应的多集分裂等式问题的迭代算法。分裂自适应步长的优点是它可以直接从迭代过程中获得,而不需要任何有关算子的谱范数的信息。在适当的条件下,我们证明了所提出的算法在Hilbert空间中的理论收敛,并通过几个数值结果证实了所提出的算法的有效性。
The split equality problem is a generalization of the split feasibility problem, meanwhile it is a special case of multiple-sets split equality problems. In this paper, we propose an iterative algorithm for solving the multiple-sets split equality problem whose iterative step size is split self-adaptive. The advantage of the split self-adaptive step size is that it could be obtained directly from the iterative procedure without needing to have any information of the spectral norm of the related operators. Under suitable conditions, we establish the theoretical convergence of the algorithm proposed in Hilbert spaces, and several numerical results confirm the effectiveness of the algorithm proposed.
