| # Bridge DDS Dataset | |
| This dataset contains bridge deals in Portable Bridge Notation (PBN) format with Double Dummy Solver (DDS) results, generated using [make-dds-dataset](https://github.com/wopdevries/make-dds-dataset). It is designed for reinforcement learning (RL) research in bridge, offering reproducible, ML-ready data. | |

| ## Dataset Structure | |
| - **Files**: | |
| - `sample_results.tsv`: TSV file with 100 deals, each with a PBN string and DDS results. | |
| - Columns: | |
| - `pbn`: String representing the deal in PBN format. | |
| - `dds_results`: Sequence of 20 integers (tricks for N, E, S, W in C, D, H, S, NT). | |
| - **Splits**: Single split (`train`) with 100 examples. | |
| - **Example**: | |
| ```python | |
| import pandas as pd | |
| data = pd.read_csv('sample_results.tsv', sep='\t') | |
| print(data.head()) |
