Abstract

We investigate the effect of R2R^2 corrections on holographic complexity growth within the framework of the Complexity=Action(CA) conjecture. By introducing a probe string into Gauss-Bonnet(GB) AdSAdS black brane background, we analyze the time derivative of the Nambu-Goto(NG) action as the holographic dual to complexity growth. Our results indicate that the complexity growth is maximized for a stationary string and is suppressed by its motion. Significantly, we identify a crossover point at specific string velocity, where the influence of R2R^2 corrections on complexity growth changes. For slow strings, stronger R2R^2 corrections enhance complexity growth, whereas for fast strings they suppress it.
