| Abstract: | This paper investigates the numerical solution of the initial value problem of ordinary differential equations, and improves the Hamming predictor-corrector iterate algorithm. Then the results of the Hamming predictor-corrector iterate algorithm and the improved Hamming iterate algorithm are compared by the numerical experiments. It proves that the improved Hamming iterate algorithm has smaller error than the Hamming iterate algorithm. |
