README
**EC-KitY** is a Python tool kit for doing evolutionary computation, and it is scikit-learn compatible.
Currently we have implemented Genetic Algorithm (GA) and tree-based Genetic Programming (GP), but EC-KitY will grow!
**EC-KitY** is:
- A comprehensive toolkit for running evolutionary algorithms
- Written in Python
- Can work with or without scikit-learn, i.e., supports both sklearn and non-sklearn modes
- Designed with modern software engineering in mind
- Designed to support all popular EC paradigms (GA, GP, ES, coevolution, multi-objective, etc').
### Dependencies
The minimal Python Version for EC-KitY is Python 3.8
The dependencies of our package are described in `requirements.txt`
For sklearn mode, EC-KitY additionally requires:
- scikit-learn (>=1.1)
### User installation
`pip install eckity`
### Documentation
API is available [here](https://api.eckity.org)
(Work in progress - some modules and functions are not documented yet.)
### Tutorials
The tutorials are available [here](https://github.com/EC-KitY/EC-KitY/wiki/Tutorials), walking you through running EC-KitY both in sklearn mode and in non-sklearn mode.
### Examples
More examples are in the [examples](https://github.com/EC-KitY/EC-KitY/tree/main/examples "examples") folder.
All you need to do is define a fitness-evaluation method, through a `SimpleIndividualEvaluator` sub-class.
You can run the examples with ease by opening this [colab notebook](https://colab.research.google.com/drive/1mpr3EGb1rpoK-_zugszQkv1sWVm-ZQiB?usp=sharing).
### Basic example (no sklearn)
You can run an EA with just 3 lines of code. The problem being solved herein is simple symbolic regression.
Additional information on this problem can be found in the [Symbolic Regression Tutorial](https://github.com/EC-KitY/EC-KitY/wiki/Tutorial:-Symbolic-Regression).
```python
from eckity.algorithms.simple_evolution import SimpleEvolution
from eckity.subpopulation import Subpopulation
from examples.treegp.non_sklearn_mode.symbolic_regression.sym_reg_evaluator import SymbolicRegressionEvaluator
algo = SimpleEvolution(Subpopulation(SymbolicRegressionEvaluator()))
algo.evolve()
print(f'algo.execute(x=2,y=3,z=4): {algo.execute(x=2, y=3, z=4)}')
```
### Example with sklearn
The problem being solved herein is the same problem, but in this case we also involve sklearn compatability - a core feature of EC-KitY.
Additional information for this example can be found in the [Sklearn Symbolic Regression Tutorial](https://github.com/EC-KitY/EC-KitY/wiki/Tutorial:-Sklearn-Compatible-Symbolic-Regression).
A simple sklearn-compatible EA run:
```python
from sklearn.datasets import make_regression
from sklearn.metrics import mean_absolute_error
from sklearn.model_selection import train_test_split
from eckity.algorithms.simple_evolution import SimpleEvolution
from eckity.creators.gp_creators.full import FullCreator
from eckity.genetic_encodings.gp.tree.utils import create_terminal_set
from eckity.sklearn_compatible.regression_evaluator import RegressionEvaluator
from eckity.sklearn_compatible.sk_regressor import SKRegressor
from eckity.subpopulation import Subpopulation
X, y = make_regression(n_samples=100, n_features=3)
terminal_set = create_terminal_set(X)
algo = SimpleEvolution(Subpopulation(creators=FullCreator(terminal_set=terminal_set),
evaluator=RegressionEvaluator()))
regressor = SKRegressor(algo)
X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.2)
regressor.fit(X_train, y_train)
print('MAE on test set:', mean_absolute_error(y_test, regressor.predict(X_test)))
```
