Arnaud Baguet contributed to the ERGO-Code/HiGHS repository by developing multi-objective optimization capabilities in HighSpy and improving build reliability across architectures. He implemented support for multiple linear objectives, enabling lexicographic optimization workflows through new API features and enhanced Python typings. To ensure robust performance, Arnaud expanded and cleaned up the test suite, introducing explicit tolerance handling and improving code readability. He also addressed cross-architecture compiler flag safety in CMake, conditionally applying performance flags to prevent build errors. His work leveraged C++, Python, and CMake, resulting in deeper test coverage, safer builds, and more flexible optimization features for downstream users.
March 2025 performance snapshot for ERGO-Code/HiGHS focused on enabling robust multi-criteria optimization workflows and strengthening test reliability. Delivered capabilities for multi-objective optimization in HighSpy, along with API and typing support, while improving test coverage and stability to reduce project risk for future feature work.

December 2024 monthly summary for ERGO-Code/HiGHS focusing on build reliability and cross-architecture flag safety. Implemented guarded application of performance optimization flags to ensure -mpopcntd and -mpopcnt are only used when supported by the compiler, preventing build errors and maintaining correct performance behavior across architectures.
