A particle swarm optimizer for discrete optimization

## Project Information

`psopt` is released under the [MIT](https://choosealicense.com/licenses/mit/),
its documentation lives at [Read the Docs](https://psopt.readthedocs.io/en/latest/),
the code on [GitHub](https://github.com/artur-deluca/psopt),
and the latest release on [PyPI](https://pypi.org/project/psopt/).

If you'd like to contribute to `psopt` you're most welcome. We've created a [little guide](CONTRIBUTING.md) to get you started!

## How to use
```python
from psopt import Permutation

# define an objective function to optimize
def obj_func(x):
    return sum([a / (i + 1) for i, a in enumerate(x)])

# list of possible candidates
candidates = list(range(1, 11))

# instantiate the optimizer
opt = Permutation(obj_func, candidates, metrics="l2")

# minimize the obj function
result = opt.minimize(selection_size=5, verbose=1, threshold=5, population=20)

# visualize the progress
result.history.plot("l2")
result.history.plot("global_best")
```

## Installation

### Python version support

Officially Python 3.6 and above

### Installing from PyPI
