A number of techniques are being actively developed by the optimization and evolutionary computing community in order to explicitly or implicitly design decomposition with respect to four facets of an optimization problem: (i) the environmental parameters, (ii) the decision variables, (iii) the objective functions, and (iv) the available computing resources. The workshop aims to be a unified opportunity to report the recent advances in the design, analysis, and understanding decomposition techniques and to discuss the current and future challenges in applying decomposition to the increasingly big and complex nature of optimization problems (e.g., large number of variables, large number of objectives, multi-modal problems, simulation optimization, uncertain scenario-based optimization) and its suitability to modern large scale compute environments (e.g., massively parallel and decentralized algorithms, large scale divide-and-conquer parallel algorithms, expensive optimization).</div><div><font face="arial, sans-serif"><br></font></div></div><div><b><font color="#ff9900" face="arial, sans-serif">*** Topics of interest</font></b></div><div><br>The workshop focus is on (but not limited to) the developmental, implementational, theoretical, and applied aspects of:<br><br><ul><li>Large-scale decomposition, e.g., decomposition in decision space, gray-box optimization, co-evolutionary algorithms, grouping and cooperative techniques, and decomposition for constraint handling.</li><li>Multi- and Many-objective decomposition, e.g., aggregation and scalarizing approaches, cooperative and hybrid island-based design, (sub-)population decomposition, and mapping.</li><li>Parallel and distributed evolutionary decomposition, e.g., scalability with respect to decision and objective spaces, divide-and-conquer decentralized techniques, distribution of compute efforts, and scalable deployments on heterogeneous and massively parallel computing environments.</li><li>General-purpose decomposition-related techniques include machine learning and model-assisted decomposition, offline and online configuration of decomposition, search-region decomposition, multiple surrogates, and parallel expensive optimization.</li><li>Understanding and benchmarking decomposition techniques.</li></ul></div><div><b style="color:rgb(255,153,0);font-family:arial,sans-serif">*** Submission</b></div><div>We invite submissions of the following types of papers:<br><ul><li>Research papers (up to 8 pages)</li><li>Position papers (up to 2 pages)</li></ul>Accepted submissions will be presented during the workshop and will appear in the GECCO Companion ACM proceedings.
