Scope and Aim:
Bilevel programming problems(BLPPs) are non-convex optimization problems with two levels, namely upper level and lower level. For such hierarchical structure, we need to fix an upper decision variable as a parameter and to solve the lower optimization problem. Such requirements make the bilevel optimization problems difficult to solve and time consuming. The majority of existing work on BLPPs is concentrated on linear BLPPs and some special nonlinear BLPPs in which all of the functions involved are convex and twice differentiable. In the context of multi-objective bilevel optimization problems, there does not exist too many studies. Most of the existing algorithms focus on approximate solution strategies and K-K-T conditions. However, these algorithms are very time consuming and strongly problem dependent.
In order to handle such problems efficiently and effectively, there is a need for theoretical as well as methodology advancements to solve single bilevel and multi-objective bilevel optimization problems.
Topics:
The special session on Nonlinear Bilevel Programming Problems will bring together researchers working on the following topics:
1.Algorithms for single bilevel-optimization problems
2.Algorithms for bilevel multi-objective optimization problems
3.Surrogate procedures to handle bilevel optimization problems
4.Approximate approaches to handle bilevel optimization problems
5.Memetic approaches to handle bilevel optimization problems
6.Theoretical results on bilevel optimization problems
7.Bilevel applications
8.Approximate procedures to handle bilevel optimization problems
