In this paper, when compared to the normal Adomian decomposition approach, we updated the method of calculating Adomian's polynomial to discover the numerical solution for a non-linear coupled Hirota system (CHS) with fewer components, improved accuracy, and faster convergence (ADM). The novel algorithm offers a viable way to computing Adomian polynomials for all types of non-linearity. We can see that these two methods are both effective for solving non-linear CHS, however, the result provided by our new algorithm is superior to that obtained by the classic Adomian decomposition method. Maple 15 was utilized to do calculations in our work.
