January, 2023 – 2023 ICSE MIP Award for Professor Abhik Roychoudhury

SemFix: Program Repair via Semantic Analysis

For a paper written in 2013, Abhik Roychoudhury is awarded the 2023 ICSE Most Influential Paper Award. The paper, titled “SemFix: Program Repair via Semantic Analysis” was written in collaboration with Hoang Duong Thien Nguyen, Dawei Qi, and Satish Chandra.

In the paper, the authors present an automated program repair method based on symbolic execution, constraint solving, and program synthesis. The requirement on the repaired code to pass a given set of tests is formulated as a constraint. The work explored the usage of symbolic execution for specification inference, when only tests are available to describe programmer intent. With this work, the authors coined the area of semantic-based program repair. The work on SemFix significantly inspired the ideas explored in our MoE Tier 3 project on Automated Program Repair!
