Popis: We study the completely synchronized states (CSSs) of a system of coupled logistic maps as a function of three parameters: interaction strength ($\varepsilon$), range of the interaction ($\alpha$), that can vary from first-neighbors to global coupling, and a parameter ($\beta$) that allows to scan continuously from non-delayed to one-time delayed dynamics. % We identify in the plane $\alpha$-$\varepsilon$ periodic orbits, limit cycles and chaotic trajectories, and describe how these structures change with the delay. These features can be explained by studying the bifurcation diagrams of a two-dimensional non-delayed map. This allows us to understand the effects of one-time delays on CSSs, e.g, regularization of chaotic orbits and synchronization of short-range coupled maps, observed when the dynamics is moderately delayed. Finally, we substitute the logistic map by cubic and logarithmic maps, in order to test the robustness of our findings.
