Shrnutí:In this paper, we present a new computational approach named the parallel inertial three-step iteration monotone hybrid algorithm (abbreviated as PITMHA), devised for addressing the common fixed point problem of a finite family of G-nonexpansive mappings in Hilbert spaces endowed with graphs. We establish a theorem demonstrating weak convergence for PITMHA. To emphasize our results, we offer an example of G-nonexpansive mappings on endowed with a graph. This brings to light a new method that allows the visualization of some convergence behaviours. Furthermore, we demonstrate the practical utility of PITMHA by applying it to solve signal recovery problems.
