 ### Custom Datasets
-For custom tasks, you can reference the code in the metagpt/ext/aflow/benchmark folder. Inherit the `BaseBenchmark` class and implement `evaluate_problem`, `calculate_score`, and `get_result_columns` to add your custom dataset benchmark. Then, add your benchmark name in `metagpt/ext/aflow/scripts/evaluator.py` and `metagpt/ext/aflow/scripts/optimizer.py` to find effective workflows for your custom dataset.
