+
+An extensive Reinforcement Learning (RL) for Combinatorial Optimization (CO) benchmark. Our goal is to provide a unified framework for RL-based CO algorithms, and to facilitate reproducible research in this field, decoupling the science from the engineering.
+
+
+RL4CO is built upon:
+- [TorchRL](https://github.com/pytorch/rl): official PyTorch framework for RL algorithms and vectorized environments on GPUs
+- [TensorDict](https://github.com/pytorch-labs/tensordict): a library to easily handle heterogeneous data such as states, actions and rewards
+- [PyTorch Lightning](https://github.com/Lightning-AI/lightning): a lightweight PyTorch wrapper for high-performance AI research
+- [Hydra](https://github.com/facebookresearch/hydra): a framework for elegantly configuring complex applications
+

+</div>
+
+We offer flexible and efficient implementations of the following policies:
+- **Constructive**: learn to construct a solution from scratch
+  - _Autoregressive (AR)_: construct solutions one step at a time via a decoder
+  - _NonAutoregressive (NAR)_: learn to predict a heuristic, such as a heatmap, to then construct a solution
+- **Improvement**: learn to improve an pre-existing solution

+</div>
+
+We provide several utilities and modularization. For example, we modularize reusable components such as _environment embeddings_ that can easily be swapped to [solve new problems](https://github.com/ai4co/rl4co/blob/main/examples/3-creating-new-env-model.ipynb).

+
+## Getting started
+<a href="https://colab.research.google.com/github/ai4co/rl4co/blob/main/examples/1-quickstart.ipynb"><img src="https://colab.research.google.com/assets/colab-badge.svg" alt="Open In Colab"></a>
+
+RL4CO is now available for installation on `pip`!
+```bash
+pip install rl4co
+```
+
+To get started, we recommend checking out our [quickstart notebook](examples/1-quickstart.ipynb) or the [minimalistic example](#minimalistic-example) below.
+
+### Install from source
+This command installs the bleeding edge `main` version, useful for staying up-to-date with the latest developments - for instance, if a bug has been fixed since the last official release but a new release hasn’t been rolled out yet:
+
+```bash
+pip install -U git+https://github.com/ai4co/rl4co.git
+```
+
+### Local install and development
+If you want to develop RL4CO we recommend you to install it locally with `pip` in editable mode:
+
+```bash
+git clone https://github.com/ai4co/rl4co && cd rl4co
+pip install -e .
+```
+
+We recommend using a virtual environment such as `conda` to install `rl4co` locally.
+
+
+
+## Usage
+
+
+Train model with default configuration (AM on TSP environment):
+```bash
+python run.py
+```
+
+> [!TIP]
+> You may check out [this notebook](examples/advanced/1-hydra-config.ipynb) to get started with Hydra!
+
+<details>
+    <summary>Change experiment settings</summary>
+
+Train model with chosen experiment configuration from [configs/experiment/](configs/experiment/)
+```bash
+python run.py experiment=routing/am env=tsp env.num_loc=50 model.optimizer_kwargs.lr=2e-4
+```
+Here you may change the environment, e.g. with `env=cvrp` by command line or by modifying the corresponding experiment e.g. [configs/experiment/routing/am.yaml](configs/experiment/routing/am.yaml).
+
+</details>
+
+
+
+
+<details>
+    <summary>Disable logging</summary>
+
+```bash
+python run.py experiment=routing/am logger=none '~callbacks.learning_rate_monitor'
+```
+Note that `~` is used to disable a callback that would need a logger.
+
+</details>
+
+
+<details>
+    <summary>Create a sweep over hyperparameters (-m for multirun)</summary>
+
+```bash
+python run.py -m experiment=routing/am  model.optimizer.lr=1e-3,1e-4,1e-5
+```
+</details>
+
+
+
+### Minimalistic Example
+
+Here is a minimalistic example training the Attention Model with greedy rollout baseline on TSP in less than 30 lines of code:
+
+```python
+from rl4co.envs.routing import TSPEnv, TSPGenerator
+from rl4co.models import AttentionModelPolicy, POMO
+from rl4co.utils import RL4COTrainer
+
+# Instantiate generator and environment
+generator = TSPGenerator(num_loc=50, loc_distribution="uniform")
+env = TSPEnv(generator)
+
+# Create policy and RL model
+policy = AttentionModelPolicy(env_name=env.name, num_encoder_layers=6)
+model = POMO(env, policy, batch_size=64, optimizer_kwargs={"lr": 1e-4})
+
+# Instantiate Trainer and fit
+trainer = RL4COTrainer(max_epochs=10, accelerator="gpu", precision="16-mixed")
+trainer.fit(model)
+```
+
+Other examples can be found on the [documentation](https://rl4co.readthedocs.io/en/latest/)!
+
+
+### Testing
+
+Run tests with `pytest` from the root directory:
+
+```bash
+pytest tests
+```
+
+### Known Bugs
+
+
+#### Bugs installing PyTorch Geometric (PyG)
+
+Installing `PyG` via `Conda` seems to update Torch itself. We have found that this update introduces some bugs with `torchrl`. At this moment, we recommend installing `PyG` with `Pip`:
+```bash
+pip install torch_geometric
+```
