Biographical note

Xinjie Yu is an associate professor of the department of electrical engineering at Tsinghua University. He received his PhD in Electrical Engineering from Tsinghua University in 2001. Then he served as a lecturer at Tsinghua University until 2005 and was promoted to the position of associate professor; a role he has held ever since. He was a visiting scholar at the Massachusetts Institute of Technology in 2003 and at the Graduate School of Information, Production and Systems of Waseda University in 2008 and 2009 separately. Dr Yu's research interests include evolutionary computation (especially genetic algorithms, evolution strategy, multimodal optimization, and multiobjective optimization) and its applications in various aspects of electrical engineering, power electronics, wireless energy transferring, etc. Mitsuo Gen is a visiting scientist at the Fuzzy Logic Systems Institute (FLSI), Iizuka, Japan, which he joined in August 2009 after retiring from his position as a professor in the Graduate School of Information, Production and Systems, Waseda University; a role he had held since April 2003. He received a PhD in Engineering from Kogakuin University in 1974 and a PhD in Informatics from Kyoto University in 2006. He worked at Ashikaga Institute of Technology for several years: as a lecturer during the period 1974–1980, an associate professor during the period 1980–1987, and as a professor during the period 1987–2003. He was a visiting associate professor at the University of Nebraska-Lincoln from 1981–1982, and a visiting professor at the University of California at Berkeley from 1999-2000, at POSTECH in Fall 2008 and at the Asian Institute of Technology in Spring 2009. His research interests include genetic and evolutionary algorithms, artificial neural networks, fuzzy logic, and their applications to scheduling, network design, logistics systems, etc. He has authored several books, such as Genetic Algorithms and Engineering Design, (1997), GeneticAlgorithms and Engineering Optimization, (2000) with Dr. R. Cheng, and Network Models and Optimization: Multiobjective Genetic Algorithm Approach, Springer, London (2008) with Dr. R. Cheng and Dr. L. Lin. He has edited Intelligent and Evolutionary Systems, Studies in Computational Intelligence, vol. 187, Springer, Heidelberg (2009) with Dr. M. Gen et al., and has published more than 200 international journal papers. His books and papers have been cited more than 5000 times by researchers throughout the world.
