Comparison plagiarism search algorithms implementations

This article offers you to familiarize with metrics which are reveal disadvantages and advantages of plagiarism search algorithms. Reviewed algorithms have the most practical value, because of their use in commercial sphere. Lack of specialized sources, which reveal all sides of similar algorithms creates problems for people, who wants to solve plagiarism problem, but who has not experience and knowledges in this sphere, to use one of reviewed algorithms. Article conducts a thorough analysis metrics time depending on various factors, answering the question of efficiency of use of an algorithm for different situations, experimentally investigating the required parameters for each algorithm for its correct working. In addition, the article describes the difference of using parameters for realization of an algorithms. All reviewed metrics held with custom author's implementation of algorithms because their essence remains the same at different implementation.
