# EGObox - Efficient Global Optimization toolbox | ||
|
||
[![pytests](https://github.com/relf/egobox/workflows/pytest/badge.svg)](https://github.com/relf/egobox/actions?query=workflow%3Apytest) | ||
[![DOI](https://joss.theoj.org/papers/10.21105/joss.04737/status.svg)](https://doi.org/10.21105/joss.04737) | ||

`egobox` package is the Python binding of the optimizer named `Egor` and the surrogate model `Gpx`, mixture of Gaussian processes, from the [EGObox libraries](https://github.com/relf/egobox?tab=readme-ov-file#egobox---efficient-global-optimization-toolbox) written in Rust. | ||
|
||
## Installation | ||
|
||
```bash | ||
pip install egobox | ||
``` | ||
|
||
### Egor optimizer | ||
|
||
```python | ||
import numpy as np | ||
import egobox as egx | ||
|
||
# Objective function | ||
def f_obj(x: np.ndarray) -> np.ndarray: | ||
return (x - 3.5) * np.sin((x - 3.5) / (np.pi)) | ||
|
||
# Minimize f_opt in [0, 25] | ||
res = egx.Egor(egx.to_specs([[0.0, 25.0]]), seed=42).minimize(f_obj, max_iters=20) | ||
print(f"Optimization f={res.y_opt} at {res.x_opt}") # Optimization f=[-15.12510323] at [18.93525454] | ||
``` | ||
|
||
### Gpx surrogate model | ||
|
||
```python | ||
import numpy as np | ||
import egobox as egx | ||
|
||
# Training | ||
xtrain = np.array([0.0, 1.0, 2.0, 3.0, 4.0]) | ||
ytrain = np.array([0.0, 1.0, 1.5, 0.9, 1.0]) | ||
gpx = egx.Gpx.builder().fit(xtrain, ytrain) | ||
|
||
# Prediction | ||
xtest = np.linspace(0, 4, 20).reshape((-1, 1)) | ||
ytest = gpx.predict(xtest) | ||
``` | ||
|
