A baseline `solution.py` already exists (it produces syntactically valid but low-quality output). Your job is to improve it.\n\n---\n\n## Evaluation\n\nYour solution is scored on **50 fixed test cases**. Final score = sum of individual case scores. **Higher is better.**\n\n---\n\n## Local Testing\n\nGenerate local random tests with `./tools/bin/gen `, using seeds in the range **0..10000** only.\n\n```bash\n# Generate a random test case (seed-based, deterministic)\n./tools/bin/gen 0 > input.txt\n\n# Run your solution\npython3 solution.py < input.txt > output.txt\n\n# Score output (Higher is better)\n./tools/bin/tester input.txt output.txt\n# Outputs to stderr: Score = \n```\n\n---\n\n## Rules\n\n- Write your solution as `solution.py` in the project root directory\n- Do NOT modify files in `tools/`\n- Use `tools/bin/gen` and `tools/bin/tester` for local testing\n- For local scoring, use only `./tools/bin/tester`; do not use `tools/src/verifier.py` for scores\n- Your program should read from stdin and write to stdout\n- Run your solution to completion and verify with the tester before finishing\n" }, "judge": { "image_tag": "96df6463f5e6", "eval_cmd": "cd /home/workspace/molecules && python3 /tmp/eval_molecules.py", "eval_timeout": 600, "parser": "score_sum", "score_direction": "maximize", "selection": "score_first", "rescale": { "kind": "piecewise_max", "baseline": 69170000.0, "rank30": 235032102.6667, "rank1": 300187365.6667, "super_anchor": 322991707.7167 } } }
