A number of techniques exist to find fixed points of nonexpansive operators by utilizing an online block of mappings at each iteration. A method is presented for a certain class of composition fixed point problems. Results on linear convergence, asymptotic behavior weak, and strong convergence are suggested. Some applications are also provided to solve problems from data science.
