The 20th International Symposium on Algorithms and Computation (ISAAC 2009) will be held during December 16-18, 2009, in Hawaii, USA. The symposium is intended to provide a forum for researchers  working in algorithms and theory of computation. Papers presenting original research in the areas of  algorithms and theory of computation are sought. Papers in relevant applied areas are also welcome. 
                                          The symposium proceedings will be published by Springer-Verlag in Lecture Notes in Computer Science (LNCS)  series. Selected papers will be invited to Journal of Combinatorial Optimization, Theoritical Computer Science, Algorithmica,  Discrete Mathematics, Algorithms and 
                                        Applications, and    International Journal of Foundations
                                        of Computer Science.  Typical, but not exclusive, topics of interest include: 
                                            - Algorithms and data structures
