ESA 2013 was organized as part of ALGO 2013, which also included the Workshop on Algorithms in Bioin- formatics (WABI), the International Symposium on Parameterized and Exact Computation (IPEC), the Workshop on Approximation and Online Algorithms (WAOA),theInternationalSymposiumonAlgorithmsandExperimentsforSen- sor Systems, Wireless Networks and Distributed Robotics (ALGOSENSORS), the Workshop on Algorithmic Approaches for Transportation Modelling, Op- timization, and Systems (ATMOS), and the Workshop on Massive Data Al- gorithms (MASSIVE). The previous symposia were held in Ljubljana (2012), Saarbru¨cken (2011), Liverpool (2010), Copenhagen (2009), Karlsruhe (2008), Eilat(2007),Zu¨rich(2006),PalmadeMallorca(2005),Bergen(2004),Budapest (2003),Rome(2002),Aarhus(2001),Saarbru¨cken(2000),Prague(1999),Venice (1998), Graz (1997), Barcelona (1996), Corfu (1995), Utrecht (1994), and Bad Honnef (1993). The ESA symposia are devoted to fostering and disseminating the results of high-quality research on the design and evaluation of algorithms and data structures.Theforumseeksoriginalalgorithmiccontributionsforproblemswith relevant theoretical and/or practical applications and aims at bringing together researchersinthecomputerscienceandoperationsresearchcommunities.Papers were solicited in all areas of algorithmic research, both theoretical and experi- mental,andwereevaluatedbytwoProgramCommittees(PC).ThePCofTrack A (Design and Analysis) selected contributions with a strong emphasis on the theoretical analysis of algorithms. The PC of Track B (Engineering and Appli- cations) evaluated papers reporting on the results of experimental evaluations and on algorithm engineering contributions for interesting applications. In response to a call for papers, the PCs received 303 submissions from 46 countries,229forTrackAand74forTrackB.All submissionswerereviewedby at least three PC members and were carefully evaluated on quality, originality, and relevance to the conference. Overall, the PCs wrote more than 900 reviews with the help of more than 450 external reviewers, who also participated in an extensive electronic discussion that led the committees of the two tracks to select69papers(53outof229inTrackAand16outof74inTrackB),yielding an acceptance rate of about 23%. In addition to the accepted contributions, the symposium featured two invited lectures by Hannah Bast (University of Freiburg, Germany) and by Claire Mathieu (CNRS, E´cole Normale Sup´erieure, France and Brown University, USA). TheEuropeanAssociationforTheoreticalComputerScience(EATCS)spon- soredabestpaperawardandabeststudentpaperaward.Theformerawardwas VI Preface shared by two papers: one by Rajesh Chitnis, La´szl´o Egri and Dani´el Marx for theircontributionon“ListH-ColoringaGraphbyRemovingFewVertices”and the other by Sander P.A. Alewijnse, Quirijn W. Bouts, Alex P. ten Brink and Kevin Buchin for their contribution entitled “Computing the Greedy Spanner in Linear Space.” The best student paper prize was awarded to Radu Curtica- pean and Marvin Ku¨nnemann for their contribution entitled “A Quantization Framework for Smoothed Analysis on Euclidean Optimization Problems.” Our warmest congratulations to all of them for these achievements! Wewishtothankalltheauthorswhosubmittedpapersforconsideration,the invited speakers,the members ofthe PCs for their hardwork,as well as the ex- ternalreviewerswhoassistedthePCsintheevaluationprocess.Weareindebted to the Organizing Committee members, who helped with the local organization of the conference. We hope that the readers will enjoy the papers published in this volume, sparking their intellectual curiosity and providing inspiration for their work. June 2013 Hans L. Bodlaender Giuseppe F.
