算法分析是对一个算法需要多少计算时间和存储空间作定量的分析。 算法（Algorithm）是解题的步骤，可以把算法定义成解一确定类问题的任意一种特殊的方法。在计算机科学中，算法要用计算机算法语言描述，算法代表用计算机解一类问题的精确、有效的方法。算法+数据结构=程序，求解一个给定的可计算或可解的问题，不同的人可以编写出不同的程序，来解决同一个问题，这里存在两个问题：一是与计算方法密切相关的算法问题；二是程序设计的技术问题。算法和程序之间存在密切的关系。分析算法可以预测这一算法适合在什么样的环境中有效地运行，对解决同一问题的不同算法的有效性作出比较。-Algorithm analysis is an algorithm requires the number of computing time and storage space for quantitative analysis. The algorithm (algorithm) is the solving step, the algorithm can be defined into solution a determined any of the class of problems in a special way. In computer science, algorithms use computer ALGOL described algorithm behalf of a class of problems with computer solutions accurate and effective method. Algorithm+ Data Structures = Programs, solving a given computable solvable problem, different people can write a different program to solve the same problem, there are two problems: first, closely related to the calculation method algorithm　program designed technical problems. There is a close relationship between the algorithms and programs. The analysis algorithm can predict that this algorithm is suitable to run in what kind of environment, and compare the effectiveness of different algorithms to solve the same problem.
