ECOM - Evolutionary Combinatorial Optimization and Metaheuristics

Description

The ECOM track aims to provide a forum for the presentation and discussion of high-quality research on metaheuristics for combinatorial optimization problems. Challenging problems from a broad range of applications, including logistics, network design, bioinformatics, engineering and business have been tackled successfully with metaheuristic approaches. In many cases, the resulting algorithms represent the state-of-the-art for solving these problems. In addition to evolutionary algorithms, the class of metaheuristics includes prominent generic problem solving methods, such as tabu search, iterated local search, variable neighborhood search, memetic algorithms, simulated annealing, GRASP and ant colony optimization.

Scope

The ECOM track encourages original submissions on the application of evolutionary algorithms and metaheuristics to combinational optimization problems. The topics for ECOM include, but are not limited to:

  • Representation techniques
  • Neighborhoods and efficient algorithms for searching them
  • Variation operators for stochastic search methods
  • Search space and landscape analysis
  • Comparisons between different techniques (including exact methods)
  • Constraint-handling techniques
  • Automated design of combinatorial optimisation algorithms
  • Characteristics of problems and problem instances


Notice that the submission of very narrowed case studies of real-life problems as well as highly specific theoretical results on the performance of evolutionary algorithms may be better suited to other tracks at GECCO.

Sarah L. Thomson

Edinburgh Napier University

Sarah L. Thomson is a lecturer at Edinburgh Napier University in Scotland. Her PhD was in fitness landscape analysis and under the supervision of Professor Gabriela Ochoa at the University of Stirling. Sarah has published extensively in landscape analysis and her work has received recognitions of its quality (shortlisted nominee for best SICSA PhD thesis in Scotland; best paper nomination at EvoCOP; being recognised as an outstanding student of EvoSTAR on two occasions). Her recent research interests lie in combining evolutionary computation and explainable AI. She has served as EvoAPPs publication chair in 2025, GECCO ECOM track co-chair in 2025, and will serve as workshops chair at PPSN 2026.

Niki van Stein

Leiden University

Niki van Stein received her PhD degree in Computer Science in 2018, from the Leiden Institute of Advanced Computer Science (LIACS), Leiden University, The Netherlands. From 2018 until 2021 she was a Postdoctoral Researcher at LIACS, Leiden University and she is currently an Assistant Professor at LIACS. Her research interests lie in explainable AI for EC and ML, surrogate-assisted optimisation and surrogate-assisted neural architecture search, usually applied to complex industrial applications.
