Jul 1, 2025July 2025 performance summary for Algumithm/study highlighting three major feature deliveries focused on scalability, efficiency, and search performance. Delivered: - Server Capacity Expansion Simulator to estimate required per-hour server expansions over a 24-hour window, enabling data-driven capacity planning and reducing overprovisioning. Commit: 1cbb2c6e4ba2f22f333ce6990534d330a2e0df53. - Minimum Camera Coverage for Vehicle Routes to optimize deployment by sorting endpoints and covering overlaps, reducing equipment costs while maintaining coverage. Commit: 5eb0cc2225741fd2ad8d10fcfc8675772df0b01d. - Lyrics Search with Wildcard Support enabling fast, wildcard-aware queries through length-based preprocessing, forward/reverse maps, and binary search for counts. Commit: cd823da37d6c9af76a948b9295b282f7e0ae5066. Overall impact: Strengthened core capabilities in capacity planning, resource optimization, and search performance, delivering measurable business value and preparing the codebase for scaling. No explicit major bug fixes are recorded for this month in the provided data; minor stability improvements were likely addressed in conjunction with feature work. Key technologies/skills demonstrated: algorithm design and optimization, data structures (maps, sorting, binary search), greedy and planning algorithms, performance-oriented coding, and traceable changes via well-scoped commits.

Jun 1, 2025June 2025 monthly summary for Algumithm/study. Delivered a cohesive Baekjoon Online Judge Solutions Library that consolidates eight recent problem implementations into a single reusable feature. The library covers diverse algorithmic domains, including lottery combination generation (6603), stock trading optimization (11501), conveyor belt robot simulation (20055), all-pairs shortest paths (1719), BFS-based connected components, expression restoration, BFS maze with two carts, and DSU-based hotel room assignment. This work enhances reuse, reduces duplication, speeds onboarding for new problems, and establishes a scalable foundation for future expansions. No high-severity bugs were reported this month; focus was on integration quality and maintainability.
