Special Session “Multiobjective Optimization with Surrogate Models” (Pre-announcement)

Pre-Announcement: 2016 IEEE WCCI/CEC Special Session 

The following proposal was provisionally accepted by the IEEE WCCI/CEC organizers:

Title: Multiobjective Optimization with Surrogate Models


Aim of this Special Session

Many real-world optimization problems involve multiple, often conflicting objectives and rely on computationally expensive simulations to assess these objectives. Such multiobjective optimization problems can be solved more efficiently if the simulations are partly replaced by accurate surrogate models. Surrogate models, also known as response surface models or meta-models, are data driven models built to simulate the processes or devices that are subject to optimization. They are used when more precise models, such as those based on the finite element method or computational fluid dynamics, spend too much time and resources. While surrogate models allow for fast simulation and assessment of the optimization objectives, they also represent an additional source of impreciseness. In multiobjective optimization, this may constitute a particular challenge when comparing candidate solutions. The aim of this special session is to bring together researchers and practitioners working with surrogate-based multiobjective optimization algorithms to present recent achievements in the field and discuss directions for further work.

Scope and topics

Prospective authors are invited to submit their original and unpublished work on all aspects of surrogate-assisted multiobjective optimization. The scope of the special session covers, but is not limited to the following topics:

  • State-of-the-art in multiobjective optimization with surrogate models
  • Theoretical aspects of surrogate-assisted multiobjective optimization
  • Novel surrogate-based multiobjective optimization algorithms
  • Comparative studies in multiobjective optimization with surrogates
  • Benchmark problems and performance measures for multiobjective optimization with surrogates
  • Real-world applications of multiobjective optimization using surrogates
