Detection of a Source Code Plagiarism in a Student Programming Competition
This addresses the problem of academic integrity in programming competitions for educators and organizers, but it appears incremental as it builds on existing plagiarism detection methods.
The authors developed a system to detect source code plagiarism in student programming competitions by analyzing mutual similarity between submitted solutions. They implemented and tested the algorithm in two actual competitions for Algorithms and Numerical Methods courses, discussing its effectiveness.
The article presents a system for testing the independence of solutions to algorithmic problems sent by students as part of the student programming competition. First, the context was discussed, as well as the need to organize programming competitions resulting from this context. Then, an algorithm was proposed to study the mutual similarity of source codes of programs sent as part of a programming competition. Since, after implementation, the algorithm was used in practice, examples of its application for detecting the plagiarism of source codes of solutions in two programming competitions conducted as part of classes on Algorithms and Numerical Methods were also presented. Finally, the effectiveness of the solutions used in the work was discussed.
