摘要

> >In this study, a comparison among three semi-analyticalnumerical integration algorithms for solving stiff ODE systems is presented.The algorithms are based on Differential Transform Method (DTM) which areMultiple-Step DTM (MsDTM), Enhanced MsDTM (E-MsDTM) and MsDTM with Padéapproximants (MsDTM-P). These methods can be classified as explicit one stepsemi-analytical numerical integration methods. The error and stability analysisof each method is presented. New important relationships among the methods areintroduced. To demonstrate our results, a comparison of the accuracy, stabilityand computational efficiency of the methods is presented through solving somelinear and nonlinear problems arising in applied science and engineering.
