Function levy_n13

pub fn levy_n13<T>(param: &[T; 2]) -> T
where
    T: Float + FromPrimitive + Sum,

Levy test function No. 13.

Defined as

$$ f(x_1,\,x_2) = \sin^2(3\pi x_1) + (x_1 - 1)^2\left[1 + \sin^2(3\pi x_2)\right] + (x_2 - 1)^2 \left[1 + \sin^2(2\pi x_2)\right] $$

where $x_i \in [-10, 10]$.

The global minimum is at $f(x_1,\,x_2) = f(1,\,1) = 0$.
