AI总结:

本文从基本原理出发,推导并讨论了最流行的线性多步法(包括Adams-Bashforth法、Adams-Moulton法和向后微分公式)的阶、相容性和各类稳定性,并总结了它们的优缺点。

摘要:

本文综述了最流行的求解常微分方程数值解的线性多步法。这些方法首先从基本原理推导,然后从阶、相容性和各类稳定性方面进行讨论。首先简要定义可能不熟悉的特定稳定性类型。所包括的方法有Adams-Bashforth法、Adams-Moulton法和向后微分公式。还描述了这些方法的优缺点。不需要太多数值方法或常微分方程的先验知识,但假定具备微积分的基本知识。

英文摘要:

A review of the most popular Linear Multistep (LM) Methods for solving Ordinary Differential Equations numerically is presented. These methods are first derived from first principles, and are discussed in terms of their order, consistency, and various types of stability. Particular varieties of stability that may not be familiar, are briefly defined first. The methods that are included are the Adams-Bashforth Methods, Adams-Moulton Methods, and Backwards Differentiation Formulas. Advantages and disadvantages of these methods are also described. Not much prior knowledge of numerical methods or ordinary differential equations is required, although knowledge of basic topics from calculus is assumed.
