During a two-month period, Hedi Bouchehda contributed to the AntaresSimulatorTeam/antares-xpansion repository by developing and refining features for the Benders algorithm used in grid expansion studies. He implemented configurable cut aggregation per iteration, enhancing convergence accuracy and enabling scalability for large planning scenarios. Using C++ and leveraging parallel computing and optimization techniques, Hedi improved both the algorithm’s configurability and the clarity of its configuration options. He also updated documentation and renamed key attributes to better reflect solver behavior, which increased code maintainability and eased onboarding. His work demonstrated depth in algorithm design and a focus on long-term code quality.

January 2026: Focused on improving Benders solver configuration clarity and code maintainability in Antares XPansion. Delivered direct documentation updates for Benders solver options and replaced AGGREGATION with NB_CUTS_PER_ITER to accurately reflect solver behavior, improving configurability, readability, and long-term maintainability. No major bugs fixed this month; efforts centered on quality of life improvements and onboarding benefits, enabling smoother future enhancements and reduced support load.
