Optimization Function using Numpy (OpFuNu)

Quick Notification

• The structure of version 1.0.0 is based on Object-Oriented Programming, which is entirely different from the previous version (<= 0.8.0).
• All CEC functions from 2005, 2008, 2010, 2013, 2014, 2015, 2017, 2019, 2020, 2021, 2022 are implemented. This version is well-organized, faster and has no more bugs.
• All old code-based functions from previous version <= 0.8.0 will be removed in version 1.0.1

Installation

Install the current PyPI release:

pip install opfunu==1.0.0

Or install the development version from GitHub:

pip install git+https://github.com/thieu1995/opfunu

How to get the function and use it

• 1st way

from opfunu.cec_based.cec2014 import F12014

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

## or

from opfunu.cec_based import F12014

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

• 2nd way

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)
