PROFILE
Davide Lusuardi
Over four months, Luca Susardi enhanced the aiplan4eu/unified-planning repository by developing and refining core planning features and infrastructure. He improved PDDL parsing and writing to support open-interval durative actions and multi-version domain objects, using Python and YAML to ensure accurate modeling and robust planner termination. Luca strengthened CI/CD pipelines and dependency management, upgrading toolchains and documentation for Python 3.10+ compatibility. He optimized code readability and performance, particularly in the FNode class, and addressed float precision issues in temporal reasoning algorithms. His work demonstrated depth in code refactoring, error handling, and process management, resulting in more reliable and maintainable planning software.

Mar 1, 2026March 2026 monthly summary for the developer: Key bug fix focused on Delta Simple Temporal Network (DSTN) distance calculation to enhance reliability of temporal reasoning in unified-planning. The change corrects the _inc_check logic to address a float precision issue, ensuring accurate distance checks and reducing the likelihood of misclassifying temporal constraints. This targeted fix improves plan feasibility correctness without impacting overall performance.

Dec 1, 2025Month: 2025-12 | Repository: aiplan4eu/unified-planning Overview: This month focused on stabilizing planning primitives, extending domain modeling, and strengthening CI reliability, enabling faster iteration and safer releases. Key features delivered: - PDDLReader Open Interval Parsing: fixed parsing of left- or right-open durative actions by introducing open-interval flags and adjusting duration constraint handling. (commit 6ac09e8aa300065c340834778d2d605b7b828acf) - PDDLWriter Domain Objects for Events and Processes: extended writer to handle domain objects for events and processes, improving representation of preconditions and effects in planning problems. (commit 8ed13a4533ceedc2771b4ab1be5986a70d34d87b) - CI and Dependency Maintenance: upgraded macOS test runner to version 15; updated tamer and enhsp to latest; refreshed contributors list. (commits 0d8a2010f0310a6642c0d7e3b8197e927ec92a7f, 490652cfcbdaad69855715b77c45856bfd29b47c, 8f8ac3088a6f34fce0e8369e8baa2340d4d0f3ab) Major bugs fixed: - Fixed PDDLReader parsing for left- and right-open durative actions (ensuring correct duration constraints and action semantics). Overall impact and accomplishments: - Improved planning accuracy for open-interval constructs, enabling more reliable planning solutions. - More expressive domain representations for events and processes, simplifying problem modeling. - Superior CI stability and compatibility with newer toolchains, reducing integration risk and accelerating development cycles. - Strengthened repository health and contributor onboarding through updated lists and dependencies. Technologies/skills demonstrated: - PDDL parsing and writing improvements, robust test/CI maintenance, dependency management, cross-repo collaboration, and contributor governance.
