Multiple choice

In the standard sufficient condition for adiabatic evolution, the required total runtime T scales with the minimum spectral gap (the energy difference E_1 - E_0 at its smallest, written delta_min) as which of the following?

T grows like 1/delta_min (inverse first power of the minimum gap)
T is independent of the minimum gap
T grows like 1/delta_min^2 (inverse square of the minimum gap)
T grows like delta_min^2 (square of the minimum gap)
