A python (Numpy) package for Un-constrained Optimization Functions
Project description
Optimization Function in Numpy (OpFuNu)
Installation
Install the current PyPI release:
pip install opfunu
Or install the development version from GitHub:
pip install git+https://github.com/thieunguyen5991/opfunu
Example
- All you need to do is: (Make sure your solution is a numpy 1-D array)
## For dimension_based
from opfunu.dimension_based.benchmark2d import Functions # import 2-d benchmark functions
import numpy as np
solution2d = np.array([-0.1, 1.5]) # Solution for 2-d benchmark
func2d = Functions() # create an object
print(func2d._bartels_conn__(solution2d)) # using function in above object
print(func2d._bird__(solution2d))
## For type_based (same as dimension_based)
from opfunu.type_based.multi_modal import Functions # import 2-d benchmark functions
import numpy as np
## For CEC
from opfunu.cec.cec2014 import Functions # import cec2014 functions
import numpy as np
cec_sol = np.array([-0.1, 1.5]) # Solution for 2-d benchmark
cec_func = Functions() # create an object
print(cec_func.C1(cec_sol)) # using function in above object from C1, ..., C30
print(cec_func.C30(cec_sol))
