Abstract

Sloth is a decision procedure for several relevant fragments of string constraints, including the straight-line fragment and acyclic formulas. In contrast to most other string solvers, Sloth is able to decide satisfiability of constraints combining concatenation, regular expressions, and transduction, all of which are essential in applications. Sloth uses succinct alternating finite-state automata (AFAs) as concise symbolic representations of string constraints, and uses model checking algorithms like IC3 for solving emptiness of the AFA.
