Artificial Intelligence Techniques for Solving Complex Optimization Problems

Optimization plays an important role in engineering problems, e.g., structural design, operations research, control engineering, many of which can be very complex due to the large number of decision variables, the large number of optimization objectives or the complex search landscape. The research objective of my PhD study is to solve such complex optimization problems using artificial intelligence techniques, including swarm intelligence techniques and evolutionary computation techniques. Within my PhD work over the past two years, I have proposed two swarm intelligence algorithms for large-scale optimization and two evolutionary algorithms for multi-/many-objective optimization. The two swarm intelligence algorithms are inspired by competition and social learning observed in social animals, while the two evolutionary algorithms are inspired by natural evolution mechanisms. My PhD research so far have resulted in four journal papers, including top journals such as IEEE Transactions on Evolutionary Computation, IEEE Transactions on Cybernetics, and Information Sciences, and five peer-reviewed conference papers including top conferences such as IEEE Congress on Evolutionary Computation and Evolutionary Multi-Criterion Optimization. Some of the proposed algorithms have already been implemented in an in-house software tool at Honda Research Institute Europe (HRI-EU) to be used by the engineers and researchers.

Bio: Ran Cheng received the B. Eng. degree from Northeastern University, Shenyang, China, in 2010. He is currently working towards the Ph.D. degree at the Department of Computer Science, University of Surrey, United Kingdom. His current research interests include multi-/many-objective optimization, estimation of distribution algorithms, and swarm intelligence. During the PhD study, he has published four journal papers in the IEEE Transactions on Evolutionary Computation, the IEEE Transactions on Cybernetics and Information Sciences; he has also published five conference papers in the IEEE Congress on Evolutionary, the Evolutionary Multi-Criterion Optimization and the UK Workshop on Computational Intelligence. He has served as a TPC member for several international conferences, and is serving as a regular reviewer for IEEE Transactions on Evolutionary Computation, IEEE Transactions on Cybernetics, Applied Soft Computing and Soft Computing.
