一句话:通过上下文感知补丁生成,缓解自动程序修复中正确补丁不在搜索空间或搜索空间过大而难以生成的问题。
基于搜索的自动程序修复在正确补丁生成数量上存在局限。论文指出两个原因:其一,正确补丁根本不在搜索空间中;其二,搜索空间过大,导致正确补丁无法在时间预算内生成,或只能在错误但看似合理的补丁之后才被生成。标题表明该工作采用上下文感知的补丁生成来改进自动程序修复,但所给摘要未展开具体方法、实现与评估细节,因此无法从现有信息判断其上下文如何获取、如何约束或排序补丁搜索,以及相对基线的修复成功率和正确补丁数量等关键结果。该工作属于自动程序修复方向,核心目标是通过引入上下文信息改善补丁生成的有效性。
The effectiveness of search-based automated program repair is limited in the number of correct patches that can be successfully generated. There are two causes of such limitation. First, the search space does not contain the correct patch. Second, the search space is huge and therefore the correct patch cannot be generated (i.e., correct patches are either generated after incorrect plausible ones or not generated within the time budget).
