This book constitutes the proceedings of the 18th International Colloquium on Theoretical Aspects of Computing, ICTAC 2021, organized by the Nazarbayev University, Nur-Sultan, Kazakhstan. The event was supposed to take place in Nur-Sultan, Kazakhstan, but due to COVID-19 pandemic is was held virtually. The 15 papers presented in this volume were carefully reviewed and selected from 40 submissions. The book also contains one invited talk in full paper length. The book deals with challenges in both theoretical aspects of computing and the exploitation of theory through methods and tools for system development. The 20 full papers presented in this volume were carefully reviewed and selected from 55 submissions. The papers cover a wide variety of topics, including: getting the best price for selling your personal data; attacking Bitcoin; optimizing various forms of model checking; synthesizing and learning algorithms; formalizing and verifying contracts, languages, and compilers; analyzing the correctness and complexity of programs and distributed systems; and finding connections from proofs in propositional logic to quantum programming languages.

This book constitutes the refereed proceedings of the 6th International Workshop on Formal Techniques for Safety-Critical Systems, FTSCS 2018, held in Gold Coast, Australia in November 2018. The 10 revised full papers presented together with an abstract of an invited talk were carefully reviewed and selected from 22 submissions. The papers are organized in topical sections on analysis and verification of Safety-Critical Systems; analysis of timed systems; semantics and analysis methods, and model transformation.

This book constitutes the refereed proceedings from the 15th International Conference on Formal Aspects of Component Software, FACS 2018, held in Pohang, South Korea, in October 2018. The 14 full papers presented together with an invited abstract and an invited paper were carefully reviewed and selected from 32 submissions. FACS 2016 is concerned with how formal methods can be used to make component-based and service-oriented software development succeed. Formal methods have provided a foundation for component-based software by successfully addressing challenging issues such as mathematical models for components, composition and adaptation, or rigorous approaches to verification, deployment, testing, and certification.

This book constitutes the revised selected papers from the 12th International Conference on Formal Aspects of Component Software, FACS 2015, held in Niteroi, Brazil, in October 2015. The 15 full papers and 2 invited papers presented in this volume were carefully reviewed and selected from 33 submissions. They are organized in topical sections, namely quality of service to withstand faults, component-based software development through research on mathematical models for components, composition and adaptation; rigorous approaches to verification, deployment, testing, and certification.

This Festschrift volume contains 28 refereed papers including personal memories, essays, and regular research papers by close collaborators and friends of Jose Meseguer to honor him on the occasion of his 65th birthday. These papers were presented at a symposium at the University of Illinois at Urbana-Champaign on September 23-25, 2015. The symposium also featured invited talks by Claude and Helene Kirchner and by Patrick Lincoln. The foreword of this volume adds a brief overview of some of Jose's many scientific achievements followed by a bibliography of papers written by Jose.

This book constitutes the refereed proceedings of the Second International Workshop, FTSCS 2013, held in Queenstown, New Zealand, in October 2013. The 17 revised full papers presented together with an invited talk were carefully reviewed and selected from 32 submissions. The papers address various topics related to the application of formal and semi-formal methods to improve the quality of safety-critical computer systems.

This book constitutes revised selected papers of the 8th International Workshop on Formal Aspects of Component Software, FACS 2011, held in Oslo, Norway in September 2011. The 18 full papers presented together with 3 invited talks were carefully reviewed and selected from 46 submissions. They cover the topics of formal models for software components and their interaction, design and verification methods for software components and services, formal methods and modeling languages for components and services, industrial or experience reports, and case studies, autonomic components and self-managed applications, models for QoS and other extra-functional properties (e.g., trust, compliance, security) of components and services, formal and rigorous approaches to software adaptation and self-adaptive systems, and components for real-time, safety-critical, secure, and/or embedded systems.
