Some Comparison of Solutions by Different Numerical Techniques on Mathematical Biology Problem

Abstract EN

We try to compare the solutions by some numerical techniques when we apply the methods on some mathematical biology problems.

The Runge-Kutta-Fehlberg (RKF) method is a promising method to give an approximate solution of nonlinear ordinary differential equation systems, such as a model for insect population, one-species Lotka-Volterra model.

The technique is described and illustrated by numerical examples.

We modify the population models by taking the Holling type III functional response and intraspecific competition term and hence we solve it by this numerical technique and show that RKF method gives good results.

We try to compare this method with the Laplace Adomian Decomposition Method (LADM) and with the exact solutions.
