Bandwidth vs BFS Width in Matrix Reordering, Graph Reconstruction, and Graph Drawing

Authors: David Eppstein, Michael T. Goodrich, and Songyu (Alfred) Liu

Published in: LIPIcs, Volume 351, 33rd Annual European Symposium on Algorithms (ESA 2025)


Abstract
We provide the first approximation quality guarantees for the Cuthull-McKee heuristic for reordering symmetric matrices to have low bandwidth, and we provide an algorithm for reconstructing bounded-bandwidth graphs from distance oracles with near-linear query complexity. To prove these results we introduce a new width parameter, BFS width, and we prove polylogarithmic upper and lower bounds on the BFS width of graphs of bounded bandwidth. Unlike other width parameters, such as bandwidth, pathwidth, and treewidth, BFS width can easily be computed in polynomial time. Bounded BFS width implies bounded bandwidth, pathwidth, and treewidth, which in turn imply fixed-parameter tractable algorithms for many problems that are NP-hard for general graphs. In addition to their applications to matrix ordering, we also provide applications of BFS width to graph reconstruction, to reconstruct graphs from distance queries, and graph drawing, to construct arc diagrams of small height.

Exploring Mutation Testing for Teaching Introductory Programming

Authors: Pedro Vasconcelos

Published in: OASIcs, Volume 133, 6th International Computer Programming Education Conference (ICPEC 2025)


Abstract
This paper proposes the use of introductory programming assignments based on mutation testing where students are asked to write tests rather than code. We believe such exercises can be used to teach code reading skills before students could write the corresponding programs on their own. Furthermore, feedback for such exercises can be automatically generated using testing tools. We have extended an existing web-based system for programming exercises with such mutation testing assignments and show some example use cases. This is on-going work that has yet to be validated in the classroom.

Enhancing Creative Thinking Through Gamification in LMS Environments

Authors: Maria João Varanda Pereira, Luís M. Alves, Adina Cocu, Sandra M. Dingli, Montse Meneses, and Ramon Vilanova

Published in: OASIcs, Volume 133, 6th International Computer Programming Education Conference (ICPEC 2025)


Abstract
Gamification in educational context involves applying game design elements and principles to enhance the learning experience. By incorporating the motivational features of games, it aims to engage students and support educational goals. The work presented in this article is part of ThinkGame Erasmus+ project. The project’s goal is to encourage the use of Learning Management System (LMS) tools, such as lessons, wikis, and online tests to create gamified experiences in programming classes. These innovative strategies are intended to boost student motivation and creativity by incorporating compelling narratives, adaptable challenges, collaborative tasks, and continuous feedback. Another important challenge addressed in the project was fostering creativity among teachers, encouraging them to transform conventional, non-gamified resources into engaging and thought-provoking activities for students. A case study composed of ten gamified experiences was developed at Polytechnic Institute of Bragança, one of the project partners, during one semester in Imperative Programming subject.

A Generative Artificial Intelligence Tool to Correct Programming Exercises

Authors: Filipe Portela

Published in: OASIcs, Volume 133, 6th International Computer Programming Education Conference (ICPEC 2025)


Abstract
This paper presents an innovative strategy for assessing programming exercises in higher education, leveraging generative artificial intelligence (GAI) to support automated grading while ensuring transparency, fairness, and pedagogical relevance. The proposed approach is framed within the TechTeach paradigm and integrates multiple tools - HackerRank for code development, Google Forms and Sheets for submission and prompt generation, and the ChatGPT API for intelligent evaluation. The correction process is personalised using student-specific variables (e.g., student ID, birth date, performance in group work), which are dynamically embedded into the statement and prompt. The GAI algorithm evaluates the code and performs authorship verification using peer-assessed effort data, enabling the detection of potential plagiarism or misuse of AI tools. A case study was conducted in the 2023/2024 edition of the Web Programming course at the University of Minho, which involved 118 students. Results indicate that the method produced consistent and meaningful grades, reflecting a balanced perception of difficulty from students. The system also includes a gamification mechanism (Grade Rescue) for managing contested cases. The achieved findings (>90% of students approved the exercise model) support the viability of GAI-based evaluation as a scalable and effective solution for programming education, while maintaining academic integrity and enhancing the student experience.
