Worked on the AntaresSimulatorTeam/antares-xpansion repository, delivering an Aggregation Mode Enhancement in Benders Simulation to improve numerical robustness and constraint handling in large-scale optimization. Addressed stability by fixing alphas in cuts and refactoring the C++ plugin interface, replacing C-style string arrays with std::vector for better memory safety and maintainability. Enhanced the reliability of Benders micro-iterations by stabilizing variable handling and integrating comprehensive tests. Focused on backend development using C++, MPI, and algorithm optimization, the work improved error handling for subproblem constraints and ensured more robust, scalable solutions for parallel computing and numerical methods in production environments.
