Abstract: In this paper, the variational iteration algorithm-II for generalized diffusion problems is theoretically constructed. Then, the sufficient conditions that ensure convergence of variational ...

Abstract: The variational iteration method (VIM) is one of the well‐known semi‐analytical methods for solving linear and nonlinear ordinary as well as partial differential equations. The main ...

ABSTRACT: This study presents a comprehensive numerical investigation of fourth-order nonlinear boundary value problems (BVPs) using an efficient and accurate computational approach. The present work ...
