--- CALL FOR PAPERS 18th International Symposium on Experimental Algorithms (SEA 2019)  June 24-29, 2019, Kalamata, Greece  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 combinatorial optimization and its applications. The preceding symposia were held in Riga, Monte Verit?, 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 of algorithm engineering techniques in the design and evaluation of algorithms and data structures. 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.   TOPICS OF INTEREST 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 Techniques Bioinformatics Branch-and-Bound Algorithms Combinatorial and Irregular Problems Combinatorial Structures and Graphs Communication Networks Complex Networks Computational Geometry Computational Learning Theory Computational Optimization Computer Systems Cryptography and Security Data Streams Data Structures Distributed and Parallel Algorithms Evaluation of Algorithms for Realistic Environments Experimental Techniques and Statistics Graph Drawing Heuristics for Combinatorial Optimization Implementation, Testing, Evaluation and Fine-tuning Information Retrieval Integer Programming Logistics and Operations Management Machine Learning and Data Mining Mathematical Programming Metaheuristic Methodologies Multiple Criteria Decision Making Network Analysis Novel Applications of Algorithms in Other Disciplines Online Problems Parallel Algorithms and Computing Railway Optimization using Algorithmic Methods Randomized Techniques Robotics Semidefinite Programming Simulation Software Repositories and Platforms for using Algorithms Telecommunications and Networking   SUBMISSION GUIDELINES The authors should submit an extended abstract not exceeding 12 pages, including figures, title, authors, affiliations, e-mail addresses, and a short abstract. References will not be counted in the page limit. At least 10-point font should be used. Authors are strongly advised to use the LaTeX style file supplied for the LIPIcs style here. Final proceedings papers must be camera-ready in this format. A clearly marked Appendix, which will not count toward the 12 page submission limit, can be included and will be read at the referees? discretion. All submissions have to be made via the EasyChair submission page for the conference at https://easychair.org/conferences/?conf=sea2019   Authors are encouraged to include a link to the source code and/or datasets to increase confidence in the reproducibility of their experiments; the code may be read and/or executed at the referees' discretion.  Papers submitted for review should represent original, previously unpublished work or surveys of important results. At the time the extended abstract is submitted to SEA, and for the entire review period, the paper (or essentially the same paper) should not be under review by any other conference with published proceedings or by a scientific journal. At least one author of each accepted paper will be expected to attend the conference and present the paper.   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 ***    PROCEEDINGS The conference proceedings will be published in the Leibniz International Proceedings in Informatics (LIPIcs) open-access series.
