Detailed Description
The Sample function 6 is defined as
(v^2 + w^24 + x^2 + y^2 + z^2).
The global minimum is: (0, 0) Initial guess: (0, 0.8)
Number of dimensions = 5

We overload the operator as is required in GenericCostFunction to calculate the cost of the function.
Behaviour: cost = v^2 + w^24 + x^2 + y^2 + z^2
Intended use : SampleCostFunction6 Func; cost = Func(const std::vector<double> x);
NOTE that the returned cost is the sqare root of the evaluation due to the fact the Nelder Mead class will square the cost.
Parameters:
- Parameters
-
x (input) vector containing coordinates of v, w, x, y and z
- Returns
- cost
