# iwopy
Fraunhofer IWES optimization tools in Python

![](Logo_IWOPY_white.svg)

## Overview
The `iwopy` package is in fact a meta package that provides interfaces to other open-source Python optimization packages out there. Currently this includes

- [pymoo](https://pymoo.org/index.html)
- [pygmo](https://esa.github.io/pygmo2/index.html)

`iwopy` can thus be understood as an attempt to provide *the best of all worlds* when it comes to solving optimization problems with Python. Obviously all the credit for implementing the invoked optimizers goes to the original package providers.

The basic idea of `iwopy` is to provide abstract base classes, that can be concretized for any kind of problem by the users, and the corresponding solver interfaces. However, also some helpful problem wrappers and an original optimizer are provided:

- Problem wrapper `LocalFD`: Calculates derivatives by finite differences
- Problem wrapper `RegularDiscretizationGrid`: Puts the problem on a Grid
- Optimizer `GG`: *Greedy Gradient* optimization with constraints

All calculations support vectorized evaluation of a complete population of parameters. This is useful for heuristic approaches like genetic algorithms, but also for evaluating gradients. It can lead to a vast speed-up and should be invoked whenever possible. Check the examples (or the API) for details.

PyPi reference: [https://pypi.org/project/iwopy/](https://pypi.org/project/iwopy/)

## Requirements
The supported Python versions are: 
- `Python 3.7`
- `Python 3.8`
- `Python 3.9`
- `Python 3.10`

## Installation

### Virtual Python environment

We recommend working in a Python virtual environment and install `iwopy` there. Such an environment can be created by
```console
python -m venv /path/to/my_venv
```
and afterwards be activated by
```console
source /path/to/my_venv/bin/activate
```
Note that in the above commands `/path/to/my_venv` is a placeholder that should be replaced by a path to a (non-existing) folder of your choice, for example `~/venv/iwopy`.

All subsequent installation commands via `pip` can then be executed directly within the active environment without changes. After your work with `iwopy` is done you can leave the environment by the command `deactivate`.

### Standard users

As a standard user, you can install the latest release via [pip](https://pypi.org/project/iwopy/) by
```console
pip install iwopy
```
This in general corresponds to the `main` branch at [github](https://github.com/FraunhoferIWES/iwopy). Alternatively, you can decide to install the latest pre-release developments (non-stable) by
```console
pip install git+https://github.com/FraunhoferIWES/iwopy@dev#egg=iwopy
```

### Developers

The first step as a developer is to clone the `iwopy` repository by
```console
git clone https://github.com/FraunhoferIWES/iwopy.git
```
Enter the root directory by `cd iwopy`. Then you can either install from this directory via
```console
pip install -e .
```
Alternatively, add the `iwopy` directory to your `PYTHONPATH`, e.g. by running
```console
export PYTHONPATH=`pwd`:$PYTHONPATH
```
from the root `iwopy` directory, and then
```console
pip install -r requirements.txt
```
