Entry Events

Events that will be used to introduce the project to students

Hackathon: The Semantic Code Quest

Organize a hackathon where students must improve the efficiency of a legacy system. They will apply semantic models to refactor the code, competing in teams to see who can achieve the best optimization results in terms of speed, resource use, and readability, fostering teamwork and creative programming skills.

Techno-Detective: Mystery of the Optimized Code

In this interactive scenario, students are techno-detectives called upon to solve the 'Mystery of the Optimized Code'. They gather clues (in the form of semantic annotations) from various 'witnesses' hidden in the codebase, challenging them to bring together their skills from formal modelling and verification courses to crack the case.
