编辑词源
编辑继承自中古英语 algorisme, augrym，派生自盎格鲁-诺曼语 algorisme, augrim，派生自中世纪拉丁语 algorismus，派生自阿拉伯语 الخُوَارِزْمِيّ (al-ḵuwārizmiyy)，源自波斯数学家 Muḥammad ibn Mūsā al-Khwārizmī，该词的意思是“来自花剌子模的人”。因为受到了无关的 古希腊语 ἀριθμός (arithmós)（同英语 arithmo-）影响，发音产生了变化（-s- > -th-）[1]。

- Informally, an algorithm is any well-defined computational procedure that takes some value, or set of values, as input and produces some value, or set of values, as output. An algorithm is thus a sequence of computational steps that transform the input into the output.
- 2013年7月26日, Leo Hickman, “How algorithms rule the world”, 出自 The Guardian Weekly, 第 189 卷, 第 7 期，第 26 页:
- The use of algorithms in policing is one example of their increasing influence on our lives. And, as their ubiquity spreads, so too does the debate around whether we should allow ourselves to become so reliant on them – and who, if anyone, is policing their use.
