Preface

This volume contains the papers presented at ICALP 2018, the 45th edition of the Inter-national Colloquium on Automata, Languages and Programming, held in Prague, CzechRepublic during July 9–13, 2018. ICALP is a series of annual conferences of the EuropeanAssociation for Theoretical Computer Science (EATCS), which first took place in 1972. Thisyear, the ICALP program consisted of three tracks:

Track A: Algorithms, Complexity, and Games,Track B: Logic, Semantics, Automata and Theory of Programming,Track C: Foundations of Networked Computation: Models, Algorithms, and InformationManagement.

In response to the call for papers, a total 502 submissions were received: 346 for track A,96 for track B, and 60 for track C. Each submission was assigned to at least three ProgramCommittee members, aided by many subreviewers. Out of these, the committee decidedto accept 147 papers for inclusion in the scientific program: 98 papers for Track A, 30 forTrack B, and 19 for Track C. The selection was made by the Program Committees basedon originality, quality, and relevance to theoretical computer science. The quality of themanuscripts was very high, and many deserving papers could not be selected.

This year ICALP also solicitated brief announcements of work in progress with substantialinterest for the community. In total 14 brief announcements were accepted for publication:10 for Track A and 4 for Track C. The selection of the brief announcements was made by theProgram Committees.

The EATCS sponsored awards for both a best paper and a best student paper for each ofthe three tracks, selected by the Program Committees.

The best paper awards were given to the following papers:

Track A: Heng Guo and Mark Jerrum. “A polynomial-time approximation algorithm forall-terminal network reliability”.Track B: Dirk Nowotka and Aleksi Saarela. “An optimal bound on the solution sets ofone-variable word equations and its consequences”.Track C: Dariusz Kowalski and Miguel A. Mosteiro. “Polynomial Counting in AnonymousDynamic Networks with Applications to Anonymous Dynamic Algebraic Computations”.

The best student paper awards, for papers that are solely authored by students, weregiven to the following papers:

Track A: Shashwat Garg. “Quasi-PTAS for Scheduling with Precedences using LPHierarchies”.Track B: Sarah Winter. “Uniformization problems for synchronizations of automaticrelations on words”.

Apart from the contributed talks and the brief announcements, ICALP 2018 includedinvited presentations by Jaroslav Nešetřil, Alexander Schwarzmann, Sam Staton and RyanWilliams. This volume of the proceedings contains all contributed papers and brief announce-ments presented at the conference together with the papers and abstracts of the invitedspeakers.

The program of ICALP 2018 also included presentation of the EATCS Award 2018 toNoam Nisan, the Gödel Prize 2018 to Oded Regev, the Presburger Award 2018 to Aleksander

The program also included a memorial session for Maurice Nivat, the founder of ICALPand EATCS, who passed away in September 2017.

Six satellite events of ICALP were held on 9 July, 2018:

Modern Online Algorithms (MOLI)Game Solving: Theory and PracticeParameterized Approximation Algorithms Workshop (PAAW)InfinityAlgorithmic Aspects of Temporal GraphsConstrained Recognition Problems

The Summer School on Algorithms and Lower Bounds was organized immediately beforeICALP during 6-9 July, 2018, with a follow-up workshop on Monday afternoon. The workshopwas a satellite ICALP workshop devoted to presentations by selected participants of theschool.

The Summer School on Discrete Mathematics was organized after the conference during16-20 July, 2018. The event was organized by the Institute of Mathematics of the CzechAcademy of Sciences and the Computer Science Institute of Charles University.

We wish to thank all authors who submitted extended abstracts for consideration, theProgram Committees for their scholarly effort, and all referees who assisted the ProgramCommittees in the evaluation process. We are also grateful to Anna Kotěšovcová fromCONFORG and to Jiří Sgall, Andreas Emil Feldmann, Tomáš Masařík, Michal Opler, JiříFiala and Jan Musílek and all the support staff of the Organizing Committee from CharlesUniversity for organizing ICALP 2018.

We are grateful for generous support from AVAST and RSJ companies which includedboth travel grants for young women researchers and students and a direct support of theconference. We thank the School of Computer Science (Charles University, Faculty ofMathematics and Physics) and Center of Excellence - Institute for Theoretical ComputerScience (project P202/12/G061 of Czech Science Foundation) for their support.

We would like to thank Jiří Sgall for his continuous support and Paul Spirakis, thepresident of EATCS, for his generous advice on the organization of the conference.
