Plenty of hard optimization problems in a wide range of areas such as health, manufacturing and production, logistics and supply chain management, energy, engineering, etc. are increasingly large and complex in terms of number of input parameters, decision variables, objective functions and landscape complexity. These problems are often tackled using optimization approaches including greedy algorithms, exact methods (dynamic programming, Branch-and-X, constraint programming, A∗, etc.) and metaheuristics (evolutionary algorithms, particle swarm, ant or bee colonies, simulated annealing, Tabu search, etc.). Solving efficiently and effectively large and complex problems requires the joint use of these approaches and massively parallel heterogeneous computing.

In addition, for many real-world problems (e.g. in engineering design) the evaluation of the objective function(s) often consist(s) of the execution of an expensive simulation as a black-box complex system. This is for instance typically the case in aerodynamics where a CFD-based simulation may require several hours. Optimization algorithms, even if combined with parallel computing, fail to solve these simulation-based optimization problems. A typical approach to deal with the computational burden is to use (instead of exact values) cheaper data-driven approximations of the objective function(s) so-called surrogates or meta-models. A wide range of surrogates was applied during the last decade including: classical regression models such as polynomial regression or response surface methodology, support vector machines, artificial neural networks (ANN), radial basis functions, and kriging or Gaussian process. ANN is probably the most prevalent of them with the recent “explosion” of the deep learning popularized thanks to GPGPUs.

The PaCOS Workshop topics include (but are not limited to) the following:
The PaCOS workshop seeks to provide an opportunity for researchers to present their original contributions on the joint use of advanced single- or multi-objective optimization methods, simulation and/or its data-driven approximation, and distributed and/or parallel multi/many-core computing, and any related issues. The PaCOS topics include (but are not limited to) the following:

- Simulation-based optimization.
- Parallel exact optimization/metaheuristics for solving complex problems on multi-core processors, accelerators/co-processors (e.g. GPU), clusters, grids/clouds, etc.
- (Parallel) hybrid algorithms combining optimization and simulation.
- (Parallel) surrogate-assisted optimization.
- Implementation issues of methods combining optimization, simulation and/or parallel computing.
- Software frameworks for the design and implementation of parallel and/or distributed simulation and/or surrogate-assisted techniques.
- Simulation-based optimization applications including healthcare, manufacturing, logistics, biological applications, advanced big data analytics, engineering design, etc.
- Computational/theoretical studies reporting results on solving complex problems using the joint use of parallel computing, optimization and simulation.

You are invited to submit original and unpublished research works on above and other topics related to synergy between parallel computing, optimization and simulation. Submitted papers must not have been published or simultaneously submitted elsewhere until it appears in HPCS proceedings, in the case of acceptance, or notified otherwise. For Regular papers, please submit a PDF copy of your full manuscript, not to exceed 8 double-column formatted pages per template, and include up to 6 keywords and an abstract of no more than 400 words. Additional pages will be charged additional fee. Submission should include a cover page with authors' names, affiliation addresses, fax numbers, phone numbers, and all authors email addresses. Please, indicate clearly the corresponding author(s) although all authors are equally responsible for the manuscript. Short papers (up to 4 pages), poster papers and posters (please refer to for posters submission details) will also be considered. Please specify the type of submission you have. Please include page numbers on all preliminary submissions to make it easier for reviewers to provide helpful comments.

Submit a PDF copy of your full manuscript to the Workshop paper submission site at . Acknowledgement will be sent within 48 hours of submission.

Conference Policies
Only PDF files will be accepted, uploaded to the submission link above. Each paper will receive a minimum of three reviews. Papers will be selected based on their originality, relevance, significance, technical soundness and clarity, presentation, language, and references. Submission implies the willingness of at least one of the authors to register and present the paper, if accepted. At least one of the authors of each accepted paper will have to register and attend the HPCS 2019 conference to present the paper at the special session as scheduled. By submitting the paper to the HPCS conference, all authors agree to abide by all HPCS conference paper submission, publication and presentation policies as well as following ethical and professional codes of conduct, including those of the professional co-sponsoring organizations. For more information, please refer to the Authors Info and Registration Info pages.

Accepted papers will be published in the Conference proceedings. Instructions for final manuscript format and requirements will be posted on the HPCS 2019 Conference web site. It is our intent to have the proceedings formally published in hard and soft copies and be available at the time of the conference. The proceedings is projected to be included in the IEEE or ACM Digital Library and indexed in all major indexing services accordingly.

Plans are underway to have the best papers, in extended version, selected for possible publication in a reputable journal as special issue (e.g. JoCS in 2018). Detailed information will soon be announced and will be made available on the conference website.

If you have any questions about paper submission or the Workshop, please contact the workshop organizers.
