| 摘 要： | 学生程序的自动修正是程序设计类大规模网络公开课亟需解决的关键问题。结合学生程序在线评测的需求，提出了基于遗传编程的学生程序修正模型，设计并实现了基于Web的便于教师和学生使用的程序自动修正系统。基于测试用例集实现程序在线评测，对评测结果中满足自动修正条件的学生程序进行错误定位，在此基础上实现自动修正。应用结果表明，该系统可以有效管理、测试学生程序、并为学生修正含有缺陷的程序提供参考，减轻了教师的负担。

| Abstract: | Automatic bug fixing of student programs is an attractive topic of massive open online programming courses. According to the requirements of online assessment of student programs, the automatic bug fixing model of student programs based on genetic programming was proposed and a web-based program fixing system was developed. Firstly, student programs were judged online based on test suite; secondly, the faults were located within student programs that satisfied with fixing conditions; lastly, the bugs were automatically fixed. The application of the system shows that it can effectively help students in testing and fixing programs, and the workload of teachers has been reduced. |
