§16§The 28th International Colloquium on Automata, Languages and Programming (ICALP 2001) was held July 8-12, 2001 in the Aldemar-Knossos Royal Village near Hersonissos on Crete, Greece. This volume contains all contributed papers presented at ICALP 2001, together with the invited lectures by Ahmed Bou- jani (Paris), Martin Gro e-Rhode (Berlin), Mogens Nielsen (Aarhus), and Ingo Wegener (Dortmund) and two of the keynote lectures, by Christos Papadimitriou and Boris Trakhtenbrot. For almost 30 years now, ICALP has been the main annual event of the European Association for Theoretical Computer Science (EATCS). The ICALP program currently consists of track A: Algorithms, Automata, Complexity, and Games and track B: Logic, Semantics, and Theory of Programming. In response to the Call for Papers, the program committee received 208 s- missions: 162 for track A, 46 for track B. The committee met on March 23/24, 2001 in Barcelona and selected 80 papers for inclusion into the scienti c program §16§.
