This book reviews recent advances in symbolic execution and its probabilistic variant and discusses how they can be used to ensure the safety and security of software systems. Symbolic execution is a systematic program analysis technique which explores multiple program behaviors all at once by collecting and solving symbolic constraints collected from the branching conditions in the program. The obtained solutions can be used as test inputs that execute feasible program paths. Symbolic execution has found many applications in various domains, such as security, smartphone applications,...

This book constitutes the proceedings of the 19th International Colloquium on Theoretical Aspects of Computing, ICTAC 2022, which took place in Tbilisi, Georgia, in September 2022.The 23 papers presented in this volume together with 2 short papers were carefully reviewed and selected from 52 submissions. The book deals with challenges in both theoretical aspects of computing and the exploitation of theory through methods and tools for system development.
