Analysis on Soccer Strategies by using LogAnalyzer3

Abstract

LogAnalyzer3 is a log analysis tool of RoboCup soccer simulation 2D league. In RoboCup, it is desirable to analyze game log files for developing a team without any human’s intuition and preconception. In this paper, we show an example of such a systematic method. Game log files include such important information for applying machine learning methods. We have developed a tool for extracting useful infor- mation in the games. LogAnalyzer3 can extract action sequences that are expressed by the gather of two continuous kick commands. In this paper, the action sequences are converted into kick distributions. This allows us to calculate dissimilarity between two action sequences.
