This paper presents the principle and formulas for these two approaches and gives algorithmic descriptions in details. 本文讨论了这两种计算方法的原理和公式并给出实施这两种算法的详细步骤。
Mathematicians were initially interested in the dividing line between what was and what was not algorithmic. 数学们起初感兴趣的是算法的有与无的界限，然而，简单地知道问题是否有解决的算法并不完事了。
