2021 Genetic and Evolutionary Computation Conference (GECCO'21)

Lille, France, July 10-14, 2021


The Analysing Algorithmic Behaviour of Optimisation Heuristics Workshop (AABOH), as part of the 2021 Genetic and Evolutionary Computation Conference (GECCO'21), invited the submission of original and unpublished research papers. Here you can download the AABOH Special Session Call for Papers (CfP) in PDF format and here as plain text file.

Optimisation and Machine Learning tools are among the most used tools in the modern world with its omnipresent computing devices. Yet, the dynamics of these tools have not been analysed in detail. Such scarcity of knowledge on the inner workings of heuristic methods is largely attributed to the complexity of the underlying processes that cannot be subjected to a complete theoretical analysis. However, this is also partially due to a superficial experimental set-up and, therefore, a superficial interpretation of numerical results. Indeed, researchers and practitioners typically only look at the final result produced by these methods. Meanwhile, the vast amount of information collected over the run(s) is wasted. In the light of such considerations, it is now becoming more evident that such information can be useful and that some design principles should be defined that allow for online or offline analysis of the processes taking place in the population and their dynamics.

Hence, with this workshop, we call for both theoretical and empirical achievements identifying the desired features of optimisation and machine learning algorithms, quantifying the importance of such features, spotting the presence of intrinsic structural biases and other undesired algorithmic flaws, studying the transitions in algorithmic behaviour in terms of convergence, any-time behaviour, performances, robustness, etc., with the goal of gathering the most recent advances to fill the aforementioned knowledge gap and disseminate the current state-of-the-art within the research community.

4. Instructions for Authors

Our workshop invites the submission of papers of at most 8 pages (excluding references), which should present original work that meets the high-quality standards of GECCO. Accepted papers appear in the ACM digital library as part of the Companion Proceedings of GECCO.

Each paper submitted to our workshop will be rigorously evaluated in a double-blind review process. Review criteria include the significance of the work, technical soundness, novelty, clarity, writing quality, relevance and, if applicable, sufficiency of information to permit replication.

Each paper accepted needs to have at least one author registered by the author registration deadline. By submitting a paper you agree to register and present at the conference in case the paper is accepted.

Papers must be submitted via the online submission system:
