An improvement of two nonstandard finite difference schemes for two population mathematical models
Taylor and Francis (2021-03-26)The aim of this paper is to design appropriate nonstandard finite difference (NSFD) schemes for two population mathematical models based on coupled nonlinear ordinary differential equations. Our work clarifies existing ... -
Dealing with variability in ecological modelling: An analysis of a random non-autonomous logistic population model
John Wiley & Sons, Ltd. (2021-05-09)This paper presents a methodology to deal with the randomness associated toecological modelling. Data variability makes it necessary to analyse the impactof random perturbations on the fitted model parameters. We conduct ... -
On the symmetrization and composition of nonstandard finite difference schemes as an alternative to Richardson's extrapolation
Taylor and Francis Group (2022-04-29)From the classical explicit Euler scheme of first order, nonstandard finite difference (NSFD) schemes were envisioned to mimic the essential properties of the governing differential equation model for every time step-size. ...
