Ian Menezes contributed to the AntaresSimulatorTeam/antares-xpansion repository by delivering three features over three months, focusing on backend development, code clarity, and optimization workflow improvements. He refactored the solver options API for clearer naming and maintainability, ensuring backward compatibility and reducing future maintenance overhead. Ian also developed documentation and supporting code to integrate trajectory investment problems into a master problem, establishing a foundation for multi-year optimization studies using Python and data modeling techniques. Additionally, he implemented a presolve step to simplify optimization sub-problems, exposing new CLI options and updating tests, which improved problem generation robustness and solution efficiency.

Sep 1, 2025September 2025 monthly summary for Antares-Xpansion development: Implemented a presolve step in the Antares-Xpansion workflow to simplify optimization sub-problems, reducing problem size and speeding up solves. The presolve was integrated into both the full run and the Benders steps, exposed via new CLI options, and accompanied by updated documentation. This work improves robustness of problem generation and enhances end-to-end run efficiency, enabling more scalable experiments. Documentation, cucumber tests, and the full-run driver were updated to cover the new path, ensuring maintainability and reliability.

Jun 1, 2025June 2025: Delivered documentation and supporting code to enable trajectory investment problem integration into a master problem for Antares XPansion. Established the groundwork for multi-year optimization by detailing options, master structure, input organization, and the mathematical formulation of the pluriannual trajectory investment problem. This work improves reusability, reduces integration effort for annual XPansion studies, and sets a maintainable foundation for future enhancements.

May 1, 2025May 2025 monthly summary for AntaresSimulatorTeam/antares-xpansion. Focused on API naming clarity and maintainability without introducing functional changes. Delivered a cross-file rename of the solver options API from get_decomposition_options to get_solver_options to reflect its purpose of retrieving solver configurations. The change preserves backward compatibility and reduces future maintenance cost by aligning naming with semantics. The work was finalized with a targeted cleanup commit to capture the refactor tail: e6a7b121f1ef0a4cde20f7fc940d033892c66aa0 ("Small left-over").
