Abstract

The paper proposes some new iterative algorithms for solving a split variational inclusion problem involving maximally monotone multi-valued operators in a Hilbert space. The algorithms are constructed around the resolvent of operator and the regularization technique to get the strong convergence. Some stepsize rules are incorporated to allow the algorithms to work easily. An application of the proposed algorithms to split feasibility problems is also studied. The computational performance of the new algorithms in comparison with others is shown by some numerical experiments.

Algorithm 1:

Initialization: Take $ x_0 \in \mathcal{H}_1 $ and two sequences $ \left\{\lambda_n\right\},\,\left\{\alpha_n\right\} \subset \left(0,+\infty\right) $.
Iterative Steps:
Step 1. Compute $ x_{n+1}=J_{\lambda_n\mathcal{B}_1}\left(x_n-\lambda_n\mathcal{A}^*(I-J_{\mathcal{B}_2})\mathcal{A}x_n-\lambda_n\alpha_n\mathcal{F}x_n\right). $
Step 2. Set $ n:=n+1 $ and return to Step 1.

Algorithm 2:

Initialization: Take $ x_0 \in \mathcal{H}_1 $ and $ \lambda_0>0 $, $ \mu \in (0,1) $. Choose a sequence $ \left\{\alpha_n\right\} \subset \left(0,+\infty\right) $ such that conditions $ \rm (C2) - (C4) $ hold.
Iterative Steps:
Step 1. Compute
$\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\left\{ \begin{array}{ll} y_n = J_{\lambda_n\mathcal{B}_1}\left(x_n-\lambda_n\mathcal{A}^*(I-J_{\mathcal{B}_2})\mathcal{A}x_n-\lambda_n\alpha_n\mathcal{F}x_n\right).\\ x_{n+1} = y_n+\lambda_n\left(\mathcal{A}^*(I-J_{\mathcal{B}_2})\mathcal{A}x_n-\mathcal{A}^*(I-J_{\mathcal{B}_2})\mathcal{A}y_n\right). \end{array} \right. $
Step 2. Update $ \lambda_n $:
$ \;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\; \lambda_{n+1} = \min \left\{\lambda_n,\frac{\mu ||x_n-y_n||}{||\mathcal{A}^*(I-J_{\mathcal{B}_2})\mathcal{A}x_n-\mathcal{A}^*(I-J_{\mathcal{B}_2})\mathcal{A}y_n||}\right\}.$
