Then we establish the weak convergence theorem of the proposed method. Using the shrinking projection method, we obtain strong convergence theorem. Moreover, we provide some numerical experiments to show the efficiency and the comparison.</p>2019-06-30T00:00:00+00:00http://www.rgnpublications.com/journals/index.php/cma/article/view/1083Coupled Random Fixed Point Theorems for Mixed Monotone Nonlinear Operators2019-07-13T13:55:25+00:00Chayut Kongbanchayut_kb@hotmail.comPoom Kumampoom.kum@kmutt.ac.thJuan Martínez-Morenojmmoreno@ujaen.es<p>In this paper, we prove the existence of a random coupled coincidence and coupled random fixed point theorems in complete separable metric space without the mixed \(g\)-monotone property.

Kitkuanwiyada.kum@rmutt.ac.thJ. Zhaowiyada.kum@rmutt.ac.thH. Zongwiyada.kum@rmutt.ac.thW. Kumamwiyada.kum@rmutt.ac.th<p>The purpose of this paper is to present accelerations of the \(S\)-algorithm. We first apply the Picard algorithm to the smooth convex minimization problem and point out that the Picard algorithm is the steepest descent method for solving the minimization problem. Next, we provide the accelerated Picard algorithm by using the ideas of conjugate gradient methods that accelerated the steepest descent method. Then, based on the accelerated Picard algorithm, we present accelerations of the \(S\)-algorithm. Under certain assumptions, our algorithm strongly converges to a fixed point with the S-algorithm and show that it dramatically reduces the running time and iteration needed to find a fixed point compared with that algorithm.</p>2019-06-30T00:00:00+00:00http://www.rgnpublications.com/journals/index.php/cma/article/view/1072On Inertial Relaxation CQ Algorithm for Split Feasibility Problems2019-07-13T13:55:25+00:00Prasit Cholamjiakprasitch2008@yahoo.comSuparat Kesornpromsuparat.ke@gmail.com<p>In this work, we introduce an inertial relaxation CQ algorithm for the split feasibility problem in Hilbert spaces.
