We study the action growth rate in the Wheeler-DeWitt (WDW) patch for a variety of D ≥ 4 black holes in Einstein gravity that are asymptotic to the anti-de Sitter spacetime, with spherical, toric and hyperbolic horizons, corresponding to the topological parameter k = 1, 0, −1 respectively. We find a lower bound inequality 1 T ∂İ WDW ∂S Q,P th > C for k = 0, 1, where C is some order-one numerical constant. The lowest number in our examples is C = (D − 3)/(D − 2). We also find that the quantity (İ WDW − 2P th ∆V th) is greater than, equal to, or less than zero, for k = 1, 0, −1 respectively. For black holes with two horizons, ∆V th = V + th − V − th , i.e. the difference between the thermodynamical volumes of the outer and inner horizons. For black holes with only one horizon, we introduce a new concept of the volume V 0 th of the black hole singularity, and define ∆V th = V + th − V 0 th. The volume V 0 th vanishes for the Schwarzschild black hole, but in general it can be positive, negative or even divergent. For black holes with single horizon, we find a relation betweeṅ I WDW and V 0 th , which implies that the holographic complexity preserves the Lloyd's bound for positive or vanishing V 0 th , but the bound is violated when V 0 th becomes negative. We also find explicit black hole examples where V 0 th and henceİ WDW are divergent.
