Special Session on Bilevel Optimization at CEC 2012

Congress on Evolutionary Computation 2012
June 10-15 2012, Brisbane, Australia

Bilevel optimization problems are special kind of optimization problems which require every feasible upper-level solution to satisfy the optimality conditions of a lower-level optimization problem. These problems are commonly found in many practical problem solving tasks which include optimal control, process optimization, game-playing strategy development, transportation problems, coordination of multi-divisional firms, and others. Due to the computation expense and other difficulties involved in handling such problems, they are often handled using approximate solution procedures. There is a need for theoretical as well as methodological advancements to handle such problems efficiently.

The aim of the special session is to give an opportunity to researchers and practitioners to discuss and exchange ideas for handling bilevel problems, which have yet not been widely explored by the evolutionary computation community. Topics of this session include (but are not limited to):

  1. Evolutionary algorithms for bilevel optimization problems
  2. Evolutionary algorithms for multi-objective bilevel optimization problems
  3. Approximate procedures to handle bilevel optimization problems
  4. Hybrid approaches to handle bilevel optimization problems
  5. Theoretical results on bilevel optimization problems
  6. Hierarchical decision making
  7. Bilevel Application Problems
