ICALP 2010, the 37th edition of the International Colloquium on Automata, Languages and Programming was held July 6-10, 2010 in Bordeaux, France. ICALP is a series of annual conference of the European Association for Th- retical Computer Science (EATCS) which?rst took place in 1972, organized by MauriceNivatandhiscolleaguesinParis.Thisyear, theprogramconsistedofthe established trackA, focusing on Algorithms, Complexity and Games, chairedby Paul G. Spirakis; Track B, focusing on Logic, Semantics, Automata and Theory of Programming, chaired by Samson Abramsky; Track C focusing this year on Foundations of Networked Computation: Models, Algorithms and Information Management, chaired by Friedhelm Meyer auf der Heide. The three Program Committees received a total of 389 submissions: 222 for TrackA,114forTrackBand53forTrackC, writtenbyauthorsfrom45di?erent countries. Of these, 60, 30 and 16, respectively, were selected for inclusion in the scienti?c program. Each paper got on average 3.5 referee reports. The Programalsoincluded six invitedtalks byPierreFraigniaud(CNRS and Univ.ParisDiderot), JeanGoubault-Larrecq(ENSCachanandLSV), Burkhard Monien (Univ. Paderborn), Joel Ouaknine (Oxford Univ. Computing Lab.), Roger Wattenhofer (ETH Zurich), and Emo Welzl (ETH Zurich). These 112 contributed and invited papers are presented in two proceedings volumes. The?rst contains the contributed papers of Track A and the invited talks of Burkhard Monien and Emo Welzl. The second volume contains the contributed papers of Tracks B and C as well as the invited talks of Pierre Fraigniaud, Jean Goubault-Larrecq, Joel Ouaknine and Roger Wattenhofer.
