title: Translating of fitness function from a meta heuristic algorithm [LOA]
body: <p><a href="http://www.sciencedirect.com/science/article/pii/S2288430015000524" rel="nofollow noreferrer"> Lion Optimization Algorithm (LOA)</a> is a newly proposed meta heuristic algorithm by Maziar Yazdani &amp; Fariborz Jolai. </p>
  
  <p>I'm having problems translating a fitness function in python3 for I had no prior knowledge whether I need import numpy or scipy library or code it manually without such imports.</p>
  
  <p>Here is the function I'm having troubles understanding with:</p>
  
  <p>&nbsp; &nbsp; &nbsp; <strong>fitness value of lion = f(Lion) = f(<em>x<sub>1</sub>,x<sub>2</sub>,x<sub>3</sub>,...,x<sub>N<sub>Var</sub></sub></em>)</strong> </p>
  
  <p>I'm wondering if I need to treat it as a function or as a line of code. Any help that would lead me to ideas are appreciated! Thank you.</p>
