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, Algorithmica, and Discrete Mathematics, Algorithms and
Applications. Typical, but not exclusive, topics of interest include:

* Algorithms and data structures
* Approximation algorithms
* Combinatorial optimization
* Computational biology
* Computational complexity
* Computational geometry
* Cryptography
* Experimental algorithm methodologies
* Graph drawing and graph algorithms
* Internet algorithms
* Online algorithms
* Parallel and distributed algorithms
* Quantum computing
* Randomized algorithms
