From: Asymptotic stability of a modified Lotka-Volterra model with small immigrations

Modified LV model with random number of immigration at regular interval. Four cases of the modified LV system (1) with random number of immigration. Parameter values: Initial x = 5, Initial y = 5, r = 0.2, a = 0.1, b = 0.3, m = 0.2, c = random(0.001, 1), d = random(0.001, 1). Results are shown for 1,500 steps, with an average of 15 runs. Random (i, j) means uniform random number between i and j.
