Challenging Researches in Economic Sciences Legal Informatics, Environmental Economics, Economics, OR and Mathematics
information sciences, environmental economics, economic sciences, systems approach to the
economic, managerial, mathematical, environmental, and legal subjects. The focus of most
articles is on the recent developments in the relevant. The set of papers in this book reflect both each theory and wide range of applications to economic and managerial models. The economic sciences is based upon an interdisciplinary education and research area of sciences economics, econometrics, statistics, information sciences, system sciences, application information sciences, operations research and legal informatics.
JADE, the values of each parameter are generated according to one probability density function (PDF) which is learned by the values in success cases where the child is better than the parent. However, search performance might be improved by learning multiple PDFs for each parameter based on some characteristics of search points. In this study, search points are divided into plural groups according to some criteria and PDFs are learned by parameter values in success cases for each group. Objective values and distances from a reference point, which is the best search point or the centroid of search points, are adopted as the criteria. The effect of JADE with group-based learning is shown by solving thirteen benchmark problems.

He also proposes networking the legal system, and the fusion of law and information technology. He is researching on realizing a legal justice through using information technology. Another is “propertization of personal information based on the ownership.”
