Function argmin_testfunctions::mccorminck

pub fn mccorminck<T: Float + FromPrimitive>(param: &[T]) -> T

McCorminck test function

Defined as

f(x_1, x_2) = (x_1 + x_2).sin() + (x_1 - x_2)^2 - 1.5*x_1 + 2.5*x_2 + 1

where x_1 \in [-1.5, 4] and x_2 \in [-3, 4].

The global minimum is at f(x_1, x_2) = f(-0.54719, -1.54719) = -1.913228.
