Improved solutions for five IHTC-2024 benchmark instances (derived records)

Five solution files for instances of the Integrated Healthcare Timetabling Competition 2024 (IHTC-2024) benchmark, each improving the best value listed on the live results table of the competition website at the date of validation (19 August 2026, re-checked 22 August 2026): i02 (1264 to 1263), i05 (12760 to 12744), m01 (3384 to 3380), m03 (6697 to 6692), m04 (3318 to 3315). All five pass the official IHTP validator with the stated objective values. Important: these are DERIVED solutions. Each was obtained by taking the corresponding best solution published on the competition website, freezing its patient-level decisions (admission day, room, operating theater), and re-optimizing the nurse-to-room assignment layer exactly (CP-SAT, status OPTIMAL). They are not solutions built from scratch: credit for the underlying patient assignments belongs to the original authors of the published solutions, unattributed on the site. The deposit includes the pipeline certificate and SHA256 checksums of every file. Author affiliation and further verified benchmark results: Team Banzai S.L. (https://team-banzai.com).
