  abstract =     "Debugging consumes significant time and effort in any
                 major software development project. Moreover, even
                 after the root cause of a bug is identified, fixing the
                 bug is non-trivial. Given this situation, automated
                 program repair methods are of value. In this paper, we
                 present an automated repair method based on symbolic
                 execution, constraint solving and program synthesis. In
                 our approach, the requirement on the repaired code to
                 pass a given set of tests is formulated as a
                 constraint. Such a constraint is then solved by
                 iterating over a layered space of repair expressions,
                 layered by the complexity of the repair code. We
                 compare our method with recently proposed genetic
                 programming based repair on SIR programs with seeded
                 bugs, as well as fragments of GNU Coreutils with real
                 bugs. On these subjects, our approach reports a higher
                 success-rate than genetic programming based repair, and
                 produces a repair faster.",
