There are more bugs in real-world programs than human programmers can realistically address. This paper evaluates two research questions: ``What fraction of bugs can be repaired automatically?'' and ``How much does it cost to repair a bug automatically?'' In previous work, we presented GenProg, which uses genetic programming to repair defects in(More)
Description Automated program repair is able to simplify the work of a software developer by a large amount. Current approaches are admittedly far from being sophisticated, though. A comparably large branch of approaches uses genetic algorithms to generate viable bug fixes/patches for previously located errors in a software project. The general idea is to(More)
