In this research, a suitable numerical simulation method is used to solve a non-linear system
that contains multi-variables and multi-parameters with absent real data. The solution to …

This research aims to numerically solve a nonlinear initial value problem presented as a
system of ordinary differential equations. Our focus is on epidemiological systems in …

A novel time-efficient (TE) numerical scheme based on the Runge-Kutta (RK) algorithm is
devised for solving linear and non-linear Volterra-type integro-differential equations (VTIDE) …

This investigation introduces a novel methodology that integrates numerical simulation with
shrinkage estimation techniques to solve systems of nonlinear equations, marking its …

The aim of our study is to solve a nonlinear epidemic model, which is the COVID-19
epidemic model in Iraq, through the application of initial value problems in the current study …

This research aims to solve the nonlinear model formulated in a system of differential
equations with an initial value problem (IVP) represented in COVID-19 mathematical …

The nature of epidemiological models is characterized by randomness in their coefficients,
while the classical or analytical and numerical methods deal with systems with fixed …

This study presents a novel application of Non-Standard Finite Difference (NSFD) Method to
solve a COVID-19 epidemic mathematical model with the impact of fear due to infection. The …
