Using Execution Paths to Evolve Software Patches

Free registration required

Executive Summary

The authors present an evolutionary approach using Genetic Programming (GP) to automatically create software repairs. By concentrating the modifications on regions related to where the bug occurs, they effectively minimize the search space complexity and hence increase the performance of the GP process. To preserve the core functionalities of the program, they evolve programs only from code in the original program. Early experimental results show their GP approach is able to fix various program defects in reasonable time.
