How to fix   Long Method   

Long Method

Small methods make your code easier to understand, in particular if combined with a good name. Besides, if your method is small, finding a good name is usually much easier.

For example, if you find yourself adding comments to a method's body, this is usually a good sign to extract the commented part to a new method, and use the comment as a starting point when coming up with a good name for this new method.

Commonly applied refactorings include:

1 
from NiaPy.algorithms import Algorithm
2 
from NiaPy.algorithms import basic as basic_algorithms
3 
from NiaPy.algorithms import modified as modified_algorithms
4 
from NiaPy.algorithms import other as other_algorithms
