--- CALL FOR PAPERS (apologies for multiple postings) *18th International Symposium on Experimental Algorithms (SEA 2019) * June 24-29, 2019, Kalamata, Greece *http://www.caopt.com/SEA2019/ <http://www.caopt.com/SEA2019/>* SEA (Symposium on Experimental Algorithms), previously known as WEA (Workshop on Experimental Algorithms), is an international forum for researchers in the area of design, analysis, and experimental evaluation and engineering of algorithms, as well as in various aspects of computational optimization and its applications. The preceding symposia were held in Riga, Monte Verità, Rio de Janeiro, Santorini, Menorca Island, Rome, Cape Cod, Dortmund, Ischia Island, Crete, Bordeaux, Rome, Copenhagen, Paris, St. Petersburg, London, and L'Aquila. SEA aims to attract papers from both the Computer Science and the Operations Research/Mathematical Programming communities. The main theme of the symposium is the role of experimentation and engineering techniques in the design and evaluation of algorithms, data structures, and computational optimization methods. SEA hosts original research works specializing in various aspects of algorithm engineering and computational optimization. Submissions should present significant contributions supported by experimental evaluation, methodological issues in the design and interpretation of experiments, the use of (meta-) heuristics, or application-driven case studies that deepen the understanding of the complexity of a problem. *TRACK ON ALGORITHM ENGINEERING AND DESIGN* Contributions solicited cover a variety of topics including but not limited to: Algorithm Engineering Algorithmic Libraries Algorithmic Mechanism Design Analysis of Algorithms Algorithms for Memory Hierarchies Algorithms for the World-Wide-Web Approximation and Randomization Techniques Branch-and-Bound Algorithms Combinatorial Structures and Graphs Complex Networks Computational Geometry Cryptography and Security Data Streams Data Structures Distributed and Parallel Algorithms Computer Systems Graph Drawing Information Retrieval Network Analysis Novel Applications of Algorithms in Other Disciplines Software Repositories and Platforms for using Algorithms Telecommunications and Networking *TRACK ON COMPUTATIONAL OPTIMIZATION AND OPERATIONS RESEARCH* Contributions solicited cover a variety of topics including but not limited to: Approximation Techniques Artificial Intelligence Bioinformatics Combinatorial Optimization Computational Learning Theory Computational Optimization Evaluation of Optimization Algorithms for Realistic Environments Experimental Techniques and Statistics Heuristics for Combinatorial Optimization Implementation, Testing, Evaluation and Fine-tuning Integer Programming Logistics and Operations Management Machine Learning and Data Mining Mathematical Programming Metaheuristic Methodologies Multiple Criteria Decision Making Online Problems Optimization Methods in Big Data Problems Parallel Algorithms and Computing Railway Optimization using Algorithmic Methods Randomized Techniques Robotics Semidefinite Programming Simulation *PROCEEDINGS AND SUBMISSION* All accepted papers of each track will be published in the proceedings as follows: Track on Algorithm Engineering and Design All accepted papers will be published in the Leibniz International Proceedings in Informatics (LIPIcs) open-access series. LaTeX template: *https://www.dagstuhl.de/en/publications/lipics/instructions-for-authors/ <https://www.dagstuhl.de/en/publications/lipics/instructions-for-authors/>* Manuscript preparation: the manuscript should not exceed 12 pages using at least 10-point font, including figures, title, authors, affiliations, e-mail addresses, and a short abstract. References will not be counted in the page limit. Track on Computational Optimization and Operations Research All accepted papers will be published in a post-conference volume of the series on Lecture Notes in Computer Science (LNCS) from Springer.

Manuscript preparation: the manuscript should not exceed 16 pages in LNCS format, including figures, title, authors, affiliations, e-mail addresses, and a short abstract. In both cases, a clearly marked Appendix, which will not count toward the page submission limit, can be included and will be read at the referees’ discretion. Final proceedings papers must be camera-ready in the corresponding format. All papers must be submitted in PDF using EasyChair through the SEA 2019 Submission System (*https://easychair.org/my/conference.cgi?conf=sea2019 <https://easychair.org/my/conference.cgi?conf=sea2019>*). The corresponding track can be selected during the submission procedure. A special issue of selected papers will be published in the ACM Journal of Experimental Algorithmics. *IMPORTANT DATES* Abstract submission: **** February 8, 2019 **** Full paper submission: **** February 15, 2019 **** Acceptance notification: **** March 29, 2019 **** Camera-ready version: **** April 12, 2019 **** Conference dates:* *** June 24-29, 2019 **** *PLENARY SPEAKER* *Dimitrios M.
