(a) The dependence of on ε with N = 4096, α = 1.0, and different initial conditions. The circles, squares, and triangles are the results for the lowest 20%, 10%, and 5% of modes initially excited. For all cases, V_n are chosen randomly from the interval (0.5, 1.5). (b) The dependence of on α with N = 4096, ε = 0.01, and different initial conditions. The circles, squares, and triangles are the results for the lowest 20%, 10%, and 5% of modes initially excited, respectively. For all cases, V_n are chosen randomly from the interval (0.5, 1.5).
