CIMO 2019

2nd International Workshop on Computational Intelligence for Massive Optimization (CIMO 2019)

July 11-12, 2019 — Lille, France

@ contact


This is the second edition of the CIMO workshop series. It will take place from July 11 to 12, 2019, on the campus of « Cité Scientifique » at the University of Lille, France. The CIMO workshop aims at bringing together researchers interested in developing integrated computational intelligence techniques into advanced (evolutionary) optimization paradigms for solving massive optimization problems. This thematic workshop targets an international audience, and was initiated within the France/Japan collaboration (MODŌ), by providing a structuring element to gather researchers with different and often multidisciplinary backgrounds. The program will consist of talks about late-breaking research reflecting the state-of-the-art of evolutionary computation for massive optimization, and will provide many opportunities to interact with other attendees in order to encourage international cooperation and to favor the education of young researchers.

Notice that CIMO 2019 is organized just before GECCO 2019, one of the main conference in evolutionary computation, that will be held in Prague (Czech Republic) at the same period (July 13-17). This makes it convenient for interested attendees to participate in both events. Prague can be reached from Paris or Brussels in about 2-3 hours by plane.

Topics of Interests

Optimization is ubiquitous to countless modern engineering and scientific applications. Today’s increasingly complex problems require to push the boundaries of existing optimization approaches, and to design innovative flexible general-purpose computational intelligence algorithms able to efficiently and effectively tackle them. Such massive optimization problems raise new important and difficult scientific challenges because of their dimensionality in terms of variables and objectives, their heterogeneity, and their expensive nature.

What? Massive optimization problems

  • Large-scale optimization — variable space dimensionality
  • Any-objective optimization — single-, multi-, and many-objective optimization
  • Cross-domain optimization — heterogeneous continuous/combinatorial/mixed representations
  • Expensive optimization — costly/simulation-based black-box evaluations

How? Massive optimization algorithms

  • Landscape-aware algorithm design/configuration/selection
  • Model-assisted and machine learning-enhanced autonomous algorithms
  • Decomposition-based and other search paradigms, and their design principles
  • Decentralized algorithms and parallel/distributed computing
