This book constitutes the refereed proceedings of the 10th Scandinavian Workshop on Algorithm Theory, SWAT 2006, held in Riga, Latvia, in July 2006. The proceedings includes 36 revised full papers presented together with 3 invited papers, addressing issues of theoretical algorithmics and applications in various fields including graph algorithms, computational geometry, scheduling, approximation algorithms, network algorithms, data storage and manipulation, combinatorics, sorting, searching, online algorithms, optimization, amd more.

ThesymposiaonFundamentalsofComputationTheoryareheldeverytwoyears. Following the tradition established at the ?rst FCT 1977, the conference brings together specialists in theoretical ?elds of Computer Science from various co- tries and stimulates mathematical research in theoretical computer science. - pics of interest for the satellite workshop onE?cientAlgorithms WEA2001 are: computational complexity, graph and network algorithms, ?ow and routing - gorithms, coloringandpartitioning, cutsandconnectivity, packingandcovering, scheduling algorithms, approximation algorithms, inapproximability results, - line problems, randomized algorithms, integer programming, semide?nite p- gramming, algorithmic geometry, polyhedral combinatorics, branch and bound algorithms, cutting plane algorithms, and various applications. The 13th FCT was held in Riga-Lielupe, August 22-24, 2001 with an - ditional day (August 25) for the satellite workshop WEA2001. The previous meetings were held in the following cities: - Poznan-K ornik, Poland, 1977 - Wendish-Rietz, Germany, 1979 - Szeged, Hungary, 1981 - Borgholm, Sweden, 1983 - Cottbus, Germany, 1985 - Kazan, Russia, 1987 - Szeged, Hungary, 1989 - Gosen-Berlin, Germany, 1991 - Szeged, Hungary, 1993 - Dresden, Germany, 1995 - Krak ow, Poland, 1997 - Iasi, Romania, 1999 Thisyearthenumberofsubmittedpaperswashigh.TheProgramCommittee decided to accept 28 submissions as regular papers and 15 submissions as short papers. Additionally, the Program Committee of WEA2001 accepted 8 papers."

Professor Jozef Gruska is a well known computer scientist for his many and broad results. He was the father of theoretical computer science research in Czechoslovakia and among the first Slovak programmers in the early 1960s. Jozef Gruska introduced the descriptional complexity of grammars, automata, and languages, and is one of the pioneers of parallel (systolic) automata. His other main research interests include parallel systems and automata, as well as quantum information processing, transmission, and cryptography. He is co-founder of four regular series of conferences in informatics and two in quantum information processing and the Founding Chair (1989-96) of the IFIP Specialist Group on Foundations of Computer Science.

This two-volume set of LNCS 7965 and LNCS 7966 constitutes the refereed proceedings of the 40th International Colloquium on Automata, Languages and Programming, ICALP 2013, held in Riga, Latvia, in July 2013. The total of 124 revised full papers presented were carefully reviewed and selected from 422 submissions. They are organized in three tracks focussing on algorithms, complexity and games; logic, semantics, automata and theory of programming; and foundations of networked computation.
