Detailed Description
Implements the Helical Valley function.
Here the goal is to find a parameter set that minimises the Helical Valley function. This function is defined as:
100{[z-10phi(x,y)]^2 + (sqrt(x^2+y^2) -1)^2} + z^2 phi = arctan (y/x)/(2*PI) for x>0
The goal is to find the values of x, y & z that give a minimum cost. In terms of the model, x = param[0], y = param[1] and z = param[2].
