Population Dynamics Simulation
Not what you're looking for?
Do the following dynamic simulation problem:
1. The following model is proposed to describe population growth in a confined space. The excess of births over natural deaths causes a growth rate of a times the current number of individuals N. Competition for food causes deaths from starvation at a rate of bN^2 . Simulate the population growth assuming:
a. a = 0.05
b. b = 0.00001
c. N = 500 at time t=0
2. Assume in problem 1 that a second species exists in the same space subject to a1=0.04, b1=0.000015, and N1=1,000 at time t=0. However interspecies fighting causes deaths to both species at a rate that is 0.000001 times the product of their numbers (0.000001N(N1) ). Extend the model to plot the population dynamics for both species.

In brief about the solution:
Sheet 1: Q1: Solution to first part.
dN/dt == delta(N)/delta_t = a*N(t) - b*N(t)^2
=> delta(N) == N(t+delta_t) - N(t) = delta_t * (a*N(t) - ...

- " In question 2, you incorrectly add in the $3.00 dividend that was just paid to determine the value of the stock price using the dividend discount model. In question 4 response, it should have also been recognized that dividend discount models are not useful if any of the parameters used in the model are inaccurate. "
