Levy function
WebMay 31, 2013 · A small Levy curve (base case) is just a straight line. So indeed, the base case is: def lev (n): if n == 0: return 'F' else: # Recursive case here But for the recursive case, you just have it call lev (n-1). You are right that you will need to do this, but you will need to do it four times, and rotate in between. Web18 rows · Functions used to evaluate optimization algorithms. In applied mathematics, …
