# Usage

```sh
pip install simplipy
```

```python
import simplipy as sp

engine = sp.SimpliPyEngine.load("dev_7-3", install=True)

# Simplify prefix expressions
engine.simplify(('/', '<constant>', '*', '/', '*', 'x3', '<constant>', 'x3', 'log', 'x3'))
# > ('/', '<constant>', 'log', 'x3')

# Simplify infix expressions
engine.simplify('x3 * sin(<constant> + 1) / (x3 * x3)')
# > '<constant> / x3'
```

More examples can be found in the [documentation](https://simplipy.readthedocs.io/).

# Performance

> Simplification efficacy and efficiency for different maximum pattern lengths (Engine: `dev_7-3`).
> Original expressions sampled with the [Lample-Charton Algorithm](https://arxiv.org/abs/1912.01412) using the following parameters:
> - 0 to 3 variables
> - 0 to 20 operators (corresponding to lengths of 0 to 41)
> - Operators:
>   - with relative weight 10: `+`, `-`, `*`, `/`
>   - with relative weight 1: `abs`, `inv`, `neg`, `pow2`, `pow3`, `pow4`, `pow5`, `pow1_2`, `pow1_3`, `pow1_4`, `pow1_5`, `sin`, `cos`, `tan`, `asin`, `acos`, `atan`, `exp`, `log`, `mult2`, `mult3`, `mult4`, `mult5`, `div2`, `div3`, `div4`, `div5`
>
> Points show bootstrapped mean and 95% confidence interval (N = 10,000).
> Orange points are within the 95% confidence interval of the shortest simplified length for the respective original length.
> Using patterns beyond a length of 4 tokens does not yield significant improvements and comes at a cost of increased simplification time.


# Development

## Setup
To set up the development environment, run the following commands:

```sh
pip install -e .[dev]
pre-commit install
```

## Tests

Test the package with `pytest`:

```sh
pytest tests --cov src --cov-report html
```

or to skip integration tests,

```sh
pytest tests --cov src --cov-report html -m "not integration"
```
