Detailed Description

template<typename S, Index M = 2>
class minitensor::GoldsteinPrice< S, M >

Goldstein-Price function \( [1+(x+y+1)^2(19-14x+3x^2-14y+6xy+3y^2)] \) \( [30+(2x-3y)^2(18-32x+12x^2+48y-36xy+27y^2)] \). Two-dimensional with several local minima; global minimum of 3 at \( (0, -1) \).
