PROBLEM 24 - 0591: The population flow between two regions, A and B, is assumed to be proportional to the difference in population density between the areas. Let N¡ (t), N2(t) be the populations in regions A and B respectively, with N1(0) = N10 and N2(0) = N20 . The natural (i.e., in %3D absence of immigration) rates of growth of the regions (per unit of time) are given by the following formulas : Case (1): N = (1) N2 = (b – %3D rN1 %3D mN2/2N20)N2 (2) Case (2): (3) N1 = k(S – N1) N2 = (4) N1 = k(S – 12N2 Case (3): %3D N1) (5) N2 = (b - (6) where r,r2,b,m,k are positive mN2/2N20)N2 constants, 0 < k< 1. Write a FORTRAN program which uses the modified Euler method to simulate this system from t = 0 to t = tf.

PROBLEM 24 - 0591: regions, A and B, is The population flow between two assumed to be proportional to the difference in population density between the areas. Let N1 (t), N2(t) be the populations in regions A and B respectively, with N1 (0) = N1o and %3D N2(0) = N20 - The natural (i.e., in absence of immigration) rates of growth of the regions (per unit of time) are given by the following formulas : Case (1): (1) rN1 N2 = (b - mN2/2N20)N2 (2) Case (2): (3) Nj = k(S - N1) N2 = (4) N1 = k(S - 12N2 Case (3): N7) (5) N2 = (b - (6) where r,r2,b,m,k are positive mN2/2N20)N2 constants, 0 < k < 1. Write a FORTRAN program which uses the modified Euler method to simulate this system from t = 0 to t = tf .
