Riki Nakamura focused on stabilizing core infrastructure in the ut-issl/s2e-core and aiplan4eu/unified-planning repositories, addressing critical bugs to improve reliability and correctness. In s2e-core, Riki resolved ambiguous namespace references in the Wings communication layer using C++ and namespace management, eliminating compile-time and runtime errors for C2a-related classes and ensuring safe downstream integration. In unified-planning, Riki enhanced the ANMLWriter workflow by fixing interval conversion logic in Python, accurately representing open and closed intervals to prevent edge-case errors in planning outputs. This work demonstrated depth in code refactoring, bug fixing, and careful attention to system stability and maintainability.

January 2025 monthly summary for aiplan4eu/unified-planning focusing on correctness and stability of ANML interval handling. Key accomplishments in this period include a critical fix to the ANML Interval Conversion right bracket logic to accurately represent open/closed intervals according to their right-side inclusivity. This change improves interval semantics across the planning pipeline and reduces edge-case errors that could propagate to downstream components. The fix was implemented as part of the ANMLWriter workflow (commit a88cf1fd1acc6029fa63d7d937f99457dce17085). Major bugs fixed include addressing a minor bug in ANMLWriter related to interval boundary handling, contributing to more predictable and stable outputs. Overall impact: The changes enhance the correctness and reliability of interval representations in the unified-planning system, lowering risk of incorrect plan generation due to boundary misinterpretation and strengthening the foundation for future features. Technologies/skills demonstrated: interval arithmetic and semantics, ANML interval handling, code-level debugging, Git-based traceability, and targeted bug fixes within the ANMLWriter and interval conversion logic.
