The aim of the annual Workshop on Algorithm Engineering and Experiments (ALENEX)istoprovideaforumforthepresentationoforiginalresearchinthe implementationandexperimentalevaluationofalgorithmsanddatastructures. ALENEX2001,thethirdintheseries,washeldinWashington,DC,onJanuary 5-6, 2001. This volume collects extended versions of the 15 papers that were selected for presentation from a pool of 31 submissions. It also includes the abstracts from the three invited speakers, who were supported by DIMACS SpecialFocusonNextGenerationNetworks. Wewouldliketotakethisopportunitytothankthesponsors,authors,and reviewers that made ALENEX 2001 a success. We would also like to thank Springer-Verlag for publishing these papers in their series ofLecture Notes in ComputerScience.
