Jan 1, 2026January 2026 RTX monthly summary: Delivered a comprehensive PathFinder overhaul that enhances reliability and breadth of path discovery across KGX variants, with concurrency improvements and robust error handling. Implemented extended hop logic (source/destination up to 3 hops, with pruning beyond 4) and integrated the catrax-pathfinder package, expanding the search space while maintaining performance. Established multi-backend support (MySQL and SQLite) and updated dependencies to reflect newer Pathfinder capabilities. Completed infrastructure and maintenance work including Biolink integration, query-control refinements, removal of deprecated scripts, and moving Curie_ngd build scripts into the Pathfinder codebase, plus outage-resilient adjustments for PloverDB. Result: more reliable, scalable pathfinding that accelerates downstream workflows and reduces manual intervention.

Jun 1, 2025June 2025 focused on delivering improvements to path representation and ranking, consolidating blocklist management, and fixing reliability issues in PathFinder. Key changes include a string representation for paths (Path.__str__) and a new path ranking formula that mitigates hub bias by dividing total path weight by the log of node degrees for multi-node paths. Additionally, ARS blocklist functionality was merged into the general ARAX blocklist system to streamline operations and governance, and a bug fix addressed duplicate results in PathFinder.

Nov 1, 2024Month: 2024-11 | RTX project (RTXteam/RTX). Delivered the PathFinder Testing & Evaluation Suite to quantitatively assess PathFinder against a DrugBank-based baseline, including an end-to-end workflow (test suite, database table for results, test execution, and visualization of containment index distributions to identify intermediate nodes in drug-disease relationships). Implemented a targeted Node ID constraint fix in SuperNodeConverter.py to ensure IDs are appended correctly to the constraint node, and cleaned up GraphToKnowledgeGraphConverter.py by removing unused imports without changing functionality. These deliverables improve evaluation accuracy, reliability, and maintainability, enabling faster iteration on PathFinder improvements while reducing risk in production deployments.
