- abstract = "Software bugs remain a compelling problem. Automated program repair is a promising approach for reducing cost, and many methods have recently demonstrated positive results. However, success on any particular bug is variable, as is the cost to find a repair. This paper focuses on generate-and-validate repair methods that enumerate candidate repairs and use test cases to define correct behaviour. We formalise repair cost in terms of test executions, which dominate most test-based repair algorithms. Insights from this model lead to a novel deterministic repair algorithm that computes a patch quotient space with respect to an approximate semantic equivalence relation. This allows syntactic and dataflow analysis techniques to dramatically reduce the repair search space. Generate-and-validate program repair is shown to be a dual of mutation testing, suggesting several possible cross-fertilisations. Evaluating on 105 real-world bugs in programs totalling 5 million lines of code LOC and involving 10000 tests, our new algorithm requires an order-of-magnitude fewer test evaluations than the previous state-of-the-art and is over three times more efficient monetarily.",
