blocks|key|1554983|text|在“牛顿方法”和“算法”中，术语“方法”在技术上没有区别。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1554984|编辑:反思一下，也许Pete是正确的，算法会终止，方法可能不会(我该和Knuth争论吗？)然而，我不认为这是大多数人会仅仅根据你使用的一个或另一个单词而做出的区分。|1554985|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

There is no technical difference between the term "method" as in "Newton's method" and "algorithm."

EDIT: On reflection, perhaps Pete is correct that algorithms terminate and methods may not (who am I to argue with Knuth?) However, I don't think that's a distinction that most people will make based only on your use of one word or the other.

blocks|key|1339389|text|我认为这只是因为算法的原始域。如果发明者有计算机科学背景，他可能更喜欢被称为算法。在数学和其他科学领域，他们可能更喜欢所谓的方法。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1339390|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

I think it is just because the origin domain of algorithm. If the inventor is in computer science background, he may prefer called algorithm. In the domain of math and other sciences, they may prefer called method.

blocks|key|1555126|text|在上下文中陈述(牛顿方法等)算法和方法之间没有本质的区别。两者都是解决问题的循序渐进的说明。在维基百科上关于牛顿方法的文章中，它说：“该算法是豪斯霍尔德方法中的第一个，哈雷方法的继任者”。边界充其量是模糊的。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1555127|在计算机科学中，算法仍然是一种逐步解决问题的方式-一组与实现无关的步骤。方法通常是指与执行某些任务的类或对象相关联的代码块-它可以潜在地实现许多算法。|1555128|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

In the context you state (Newton's method, etc.) there is no essential difference between an algorithm and a method. Both are sets step-by-step instructions for solving a problem. In the Wikipedia article on Newton's Method, it states "The algorithm is first in the class of Householder's methods, succeeded by Halley's method". The boundary is blurry at best.

In computer science an algorithm still is a step-by-step manner towards solving a problem - an implementation-agnostic set of steps. A method commonly refers to a chunk of code associated with a class or object that does some task - it can implement many algorithms potentially.

blocks|key|1339557|text|在我看来，方法是一个比算法更一般的概念，或多或少可以是任何东西，例如将数据写入文件。由于某个事件或某个逻辑表达式而应该发生的任何事情。此外，“方法”和“算法”这两个词的含义可以根据它们在什么上下文中使用而有所不同。它们可能被用来描述同样的事情。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1339558|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

In my opinion, a method is a more general concept than algorithm and can be more or less anything, e.g. writing data to a file. Just about anything that should happen due to an event or to some logical expression. Also, the meaning of the words "method" and "algorithm" can vary depending on in what context they are used. They might be used to describe the same thing.

blocks|key|1555345|text|关于Ford-Faulkerson方法，CLRS称其为方法而不是算法，因为“它包含具有不同运行时间的几个实现”第651页。第2版|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1555346|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Regarding the Ford-Faulkerson Method, CLRS calls it method rather than algorithm because "it encompasses several implementation with different running time"[pp 651. 2nd editon]

blocks|key|1555428|text|算法就像一个公式，一步一步地解决任何特定的问题，对任何一步都没有歧义，并且必须有一个终点。方法论是任何解决方案的更一般形式。它提供了一种如何解决任何问题的方法，但在算法中，这种方法更精确地表示为解决方案。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1555429|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Algorithm is just like a formula to solve any particular problem step by step,with no ambiguity to any step, and must have some ending point. methodology is more general form of any solution. it provided a way how to solve any problem but in algorithm the way is more precisely formulated towards solution.

blocks|key|1339801|text|一个过程可以永远持续下去。其中，作为一种算法，将最终终止并精确定义每个步骤。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1339802|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

A procedure can go on forever.
Where as an Algorithm, will eventually terminate and will have each step precisely defined.

blocks|key|1555534|text|方法类似于策略，算法类似于战术。例如:在战争中，你制定了一个接管一个国家的战略(方法)：首先占领港口，向西推进，然后包围首都，等等。这个战略分为几个战术阶段(算法)：首先，一步一步地告诉士兵他们将如何占领港口；然后，告诉士兵必须如何向西推进；然后，士兵包围城市的确切步骤，等等。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1555535|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Method is analogous to a strategy, algorithm is analogous to the tactics. An example: in war, you develop a strategy (method) to take over a country: take ports first, advance west on land, then surround capital, etc. This strategy is divided in several tactical stages (algorithms): first, one that tells the soldiers step by step exactly how they are going to take the ports; then, one that tell the soldiers how they must advances west; then, one with the exact steps for the soldiers to surround the city, etc.

How do you differentiate between an algorithm and a method? Why dont we call Newton's Method or Ford-Faulkerson method Algorithms? What are a properties of a good algorithm and what qualifies a method as an algorithm?

What is the difference between an Algorithm and a Method
