TY - JOUR AU - Batiha, Khaled PY - 2007 TI - Numerical Solutions of the Multispecies Predator-Prey Model by Variational Iteration Method JF - Journal of Computer Science VL - 3 IS - 7 DO - 10.3844/jcssp.2007.523.527 UR - https://thescipub.com/abstract/jcssp.2007.523.527 AB - The main objective of the current work was to solve the multispecies predator-prey model. The techniques used here were called the variational iteration method (VIM) and the Adomian decomposition method (ADM). The advantage of this work is twofold. Firstly, the VIM reduces the computational work. Secondly, in comparison with existing techniques, the VIM is an improvement with regard to its accuracy and rapid convergence. The VIM has the advantage of being more concise for analytical and numerical purposes. Comparisons with the exact solution and the fourth-order Runge-Kutta method (RK4) show that the VIM is a powerful method for the solution of nonlinear equations.
