| 1 | Vanand Gasparyan | [OpenAI Codex 5.2] Core-DP Knapsack Solver (Greedy + "Core" Exact Optimization) | It builds a strong initial solution with value/weight greedy, then performs an exact dynamic programming optimization on a small "core" set (the least-attractive chosen items + the most-attractive unchosen items). This captures most of the optimality gap while keeping runtime practical even for 100k items. |
| 2 | Vanand Gasparyan | [Claude Opus 4.6] Adaptive Hybrid Knapsack Optimizer | High-performance 0-1 Knapsack solver that adaptively selects between exact dynamic programming and branch-and-bound with greedy initialization and local search improvement. Guarantees optimal solutions for DP-feasible instances; produces near-optimal solutions for larger ones. |
