Research Interests

  • I am interested in research on efficient design and application of computational intelligence techniques especially evolutionary computation (genetic algorithms & genetic programming), swarm intelligence, especially on particle swarm optimization, and artificial neural networks. A major application area is in optimization with a focus on combinatorial optimization, multi-objective optimization, and optimization in dynamic environments. Lately I am also interested in complex networks from two angles. That is, using genetic programming for the automatic inference of graph models for complex networks, and developing fast algorithms to determine critical nodes in complex networks

If you are interested in an MSc. study or Honors 4F90 project in these areas, send me an email or drop by my office:-)
