论算法的逻辑特征及其方法论意义

本文认为算法在科学研究中具有普遍意义，解决科学研究中的问题需要一定的方法，但“方法”这一概念含义广泛而不具体，而算法与一般方法相比，则更具体，更精确，因为它是能行的、可操作的。能解决某个科学上的问题，实质上就是意味着掌握了或找到了某种算法，某一问题的可解性意味着能够找到一个适当的算法，而某一问题的不可解性则意味着不可能找到一个适当的算法，或证明这样的算法不存在，在科学史上，很多研究工作的任务和目的，就是要寻找解决某个问题的算法。

On the logical features of algorithm and its methodological significance

Algorithm has its practical significance in the scientific research. Thesolution to a problem in sciernce needs an algorithm, which is more specific and accurate, rather than a method, which has a more general meaning. As a matter of fact, the solution to a scientific problem means having gotten a good mastery of or found an algorithm; in other words, the fact that a problem can be solved means that we can find an appropriate solution, or vice versa. In the history of science, the goal of many researchesis to find out an algorithm for the problem.
