نویسندگان

چکیده

Abstract Symbiotic-Witch is a new tool for checking violation witnesses in the GraphML-based format used at SV-COMP since 2015. Roughly speaking, symbolically executes given program with Klee and simultaneously tracks set of nodes witness automaton can be in. Moreover, it reads return values nondeterministic functions specified uses them to prune symbolic execution. The confirmed if execution reaches an error current contains matching node. currently supports reachability safety , memory cleanup overflow properties.
