Nov 1, 2025Month: 2025-11 — Jihye511/Ssafy_Algo_Study. This period delivered substantial business value through core platform enhancements, batch optimization, and expanded problem solutions. Key features delivered: (1) PGS: Core Problem Solving Platform — initial setup, problem set management, and basic instrumentation enabling easier problem curation and visibility into usage. (2) BOJ batch optimization and implementation improvements across a broad set of problems (e.g., 15961, 1197, 1931, 13913, 2234, 1520, 1600, 17619, 1956, 2629, 14725, 2473, etc.), with measurable runtime improvements captured in commit notes. (3) BOJ Problem Solutions: implementations for 6087, 1238, 2252, and 14427. (4) PGS Problem Solutions: implementations for 17684 and 42888. Major bugs fixed: stabilized batch pipelines and corrected solver edge cases across BOJ problems, improved correctness and consistency of instrumentation, and addressed edge-case handling in problem set management. Overall impact and accomplishments: accelerated problem solving workflows, improved scalability of batch problem processing, enhanced reliability and traceability through instrumentation, and created a solid foundation for faster onboarding and benchmarking. Technologies/skills demonstrated: algorithm optimization, batch processing, platform instrumentation, problem-solving mindset, performance profiling, and Git-based traceability.
