 # CP-Bench: A dataset for evaluating LLM-driven constraint modelling
 
 [![Hugging Face Space](https://img.shields.io/badge/Leaderboard-HF%20Space-blue?logo=huggingface)](https://huggingface.co/spaces/kostis-init/CP-Bench-Leaderboard)
 
-This dataset is designed to faciliate the evaluation of LLM-based methods for translating natural language problem descriptions into accurate constraint specifications. It contains diverse combinatorial problems, and is sourced from various well-established sources from the Constraint Programming community.

-## Splits
+## Dataset Versions
 
-You will notice that the dataset contains two splits (which are not exactly splits, but rather two different versions of the dataset):
-- `original`: The original dataset, which contains all problems, including those with known issues.
-- `verified`: A version of the dataset that contains problems that did not have any severe issues.
+> **_tl;dr:_** Use `v2`, it's the latest!
 
-The split `train` also exists for backwards compatibility, and it is identical to the `original` split.
+You will notice that the dataset contains various splits (which are not exactly splits, but rather different versions of the dataset):
+- `v1`: The original dataset, which contains all problems initially designed, including those with known issues.
+- `v1-verified`: A stripped-down version of the original dataset (v1) that contains only the problems that did not have any severe issues.
+- `v2`: The latest version of the dataset, which includes additional problems and fixes to the issues found in v1. It is the recommended version for use.

-# Dataset Breakdown
+## Dataset Breakdown (v2)
 
 The dataset contains problems from the following sources:
 
 - `aplai_course`: Problems from the APLAI course of KU Leuven, 2023-2024. As modelled [here](https://github.com/kostis-init/CP-LLMs-ICL/tree/main/data/APLAI_course).
+- `complex_or`: Problems from the [Complex OR repository](https://github.com/xzymustbexzy/Chain-of-Experts)
 - `cpmpy_examples`: Problems from the [CPMpy repository](https://github.com/CPMpy/cpmpy/tree/master/examples)
   - All included, except for the ones that require enumeration of all solutions (e.g. `solveAll`).
 - [`csplib`](https://www.csplib.org/Problems/)
   - For now, only the ones modelled in the [CPMpy repository](https://github.com/CPMpy/cpmpy/tree/master/examples/csplib) are included, and the ones modelled by [Hakan Kjellerstrand](http://www.hakank.org/cpmpy/).
 - `hakan_examples`: Models created by [Hakan Kjellerstrand](http://www.hakank.org/cpmpy/)
-  - In progress with alphabetical order. Currently, includes all problems until `crypta.py`, excluding the following:
+  - In progress with alphabetical order, excluding the following:
     - Those already modelled from other sources (e.g. aplai_course, cpmpy_examples, csplib)
     - Those that contain `solveAll` (counting solutions).
     - Global constraints tests, e.g. http://www.hakank.org/cpmpy/atmost_test.py

 ## Diversity
 
 We attempted to include unique problems from different sources, in order to provide a diverse set of problems.
 However, as this was a manual process, there might be duplicates or similar problems. If you notice any issues, please let us know.

+Here is a list of the changed files made to the original (v1) CP-bench dataset, focusing on the removal of instances with critical issues.
+The resulted verified dataset is available in `dataset_verified.jsonl`. All these issues are fixed in the latest version of the dataset, `v2`.
