This library is a maintenance version, a fork of [OPFUNU (Optimization Reference Functions in NUMPy)](https://github.com/thieu1995/opfunu). Is one of the most comprehensive Python libraries of numerical optimization reference functions. It contains all the functions from the CEC competitions of 2005, 2008, 2010, 2013, 2014, 2015, 2017, 2019, 2020, 2021, and 2022. In addition, it implements over 300 traditional functions with varying dimensions.

# Installation and Usage

### Install with pip

Install the [current PyPI release](https://pypi.python.org/pypi/opfunu-core):
```sh
$ pip install opfunu-core
```

Install from Github:
```sh
$ pip install git+https://github.com/ltsim/opfunu-core
```

After installation, you can import and check version of Opfunu:

```sh
$ python
>>> import opfunu
>>> opfunu.__version__

>>> dir(opfunu)
>>> help(opfunu)

>>> opfunu.FUNC_DATABASE      # List all name_based functions
>>> opfunu.CEC_DATABASE       # List all cec_based functions
>>> opfunu.ALL_DATABASE       # List all functions in this library

>>> opfunu.get_functions_by_classname("MiShra04")
>>> opfunu.get_functions_based_classname("2015")
>>> opfunu.get_functions_by_ndim(2)
>>> opfunu.get_functions_based_ndim(50)

>>> opfunu.get_name_based_functions(ndim=10, continuous=True)
>>> opfunu.get_cec_based_functions(ndim=2)
```

Let's go through some examples.

### Examples

How to get the function and use it

#### 1st way

```python
from opfunu.cec_based.cec2014 import F12014

func = F12014(ndim=30)
func.evaluate(func.create_solution())

## or

from opfunu.cec_based import F102014

func = F102014(ndim=50)
func.evaluate(func.create_solution())
```

#### 2nd way

```python
import opfunu

funcs = opfunu.get_functions_by_classname("F12014")
func = funcs[0](ndim=10)
func.evaluate(func.create_solution())

## or

all_funcs_2014 = opfunu.get_functions_based_classname("2014")
print(all_funcs_2014)
```
