Experimental and Efficient Algorithms Second International Workshop, WEA 2003, Ascona, Switzerland, May 26-28, 2003, Proceedings

 This book constitutes the refereed proceedings of the Second International Workshop on Experimental and Efficient Algorithms, WEA 2003, held in Ascona, Switzerland in May 2003.

The 19 revised full papers presented together with 3 invited contributions were carefully reviewed and selected from 40 submissions. The focus of the volume is on applications of efficient algorithms for combinatorial problems.
