[General] First Call for Papers to the GCR'09 Track in SAC'09

FIRST CALL FOR PAPERS Geometric Constraints and Reasoning a technical track of The International ACM Symposium on Applied Computing SAC2009 March 8-12, 2009 Waikiki Beach, Honolulu, Hawaii, USA Geometric Constraints and Reasoning (GCR) is a technical track of the International Symposium on Applied Computing (see http://www.acm.org/conferences/sac/sac2009). For the past twenty years the ACM Symposium on Applied Computing (SAC) has been a primary forum for applied computer scientists, computer engineers and application developers to gather, interact, and present their work. SAC is sponsored by the ACM Special Interest Group on Applied Computing (SIGAPP), its proceedings are published by ACM in both printed form and CD-ROM; they are also available on the web through ACM's Digital Library. More information about SIGAPP and past SACs can be found at URL: http://www.acm.org/sigapp. As a special track of SAC, the GCR is devoted to geometric reasoning taken in a broad sense. Initially, this track focused on geometric constraint solving but it appears that geometric computing and reasoning is closely related to this topic. Our aim is then to widen the audience and to make GCR a place where the communities of geometric constraint solving, computer aided deduction in geometry and related disciplines can meet and have fruitful exchanges. See http://www.lsi.upc.edu/~robert/gcr2009/gcr2009.html. SAC 2009 is also an opportunity to attend tracks related to GCR, about combinatorial optimization, constraint programming (non geometrical constraints), graph algorithms, numerical methods or interval analysis, etc. TOPICS Specific topics of interest for the GCR track include, but are not limited to, the following: * Resolution of geometric constraints, with computer algebra, numerical analysis, interval analysis, logical approaches (e.g. provers), or other methods. * Proving geometric theorems with logical approaches, deductive databases, Computer Algebra, etc. * Decomposition of systems of geometric constraints. * Mixing geometric and non geometric constraints (combinatorial or logical), white boxes, black boxes, geometric constraints and constraints programming. * Detection of dependences between constraints, debugging geometric constraints. * Constrained curves, surfaces, blends. * Exotic (eg non cartesian) formulations of constraints. * Comparison of resolution methods or constraints formulations for the same problems. * Mathematical background: combinatorial rigidity, graph theory, matroid theory, computer algebra (polynomial systems, dimension of ideals). * Applications in Computer Graphics, CAD-CAM, robotics, mechanism design, chemistry (eg molecule configurations), photogrammetry, virtual reality. * Sensitivity to parameters vales and other robustness issues, * Geometry of computations: using topological ad geometrical ideas in provers. * Dynamic geometry, pedagogical purposes, generating explanations, examples, counter examples. * Computer-human interfaces for geometric constraints. * Geometric constraints and data exchange. * Topological constraints, eg optimal curves or surfaces with prescribed, topology (homology, homotopy, isotopy). * Shape optimization. * Integration of geometric solvers into modelers, solvers architecture. * Geometric constraints and Human Computer interfaces. * Persistent naming problem and geometric modeling by constraints. Authors are invited to contribute original papers in the listed or other realted topics in the following categories of submissions: 1) Original and unpublished research work. 2) Reports of innovative applications to the arts, sciences, engineering, and business areas. 3) Reports of successful technology transfer to new problem domains. 4) Reports of industrial experience and demos of new innovative systems. All submissions will be peer reviewed. Papers will be selected based on their originality, timeliness, significance relevance and clarity of presentation. IMPORTANT DATES * August 16, 2008: Paper submissions * October 11, 2008: Author notification of acceptance/rejection * October 25, 2008: Camera-ready copy of accepted papers SUBMISSION INSTRUCTIONS * Submissions will be in electronic format, via the website http://sac.cs.iupui.edu/SAC2009/ * Submissions must follow the template that can be downloaded from http:www.acm.org/conferences/sac/sac2009/downloads09.htm * To facilitate blind review, papers should include in the first page just the title.
