WebOct 12, 2024 · In this section, we will explore how to solve a convex univariate function optimization problem. First, we can define a function that implements our function. In this case, we will use a simple offset version of the x^2 function e.g. a simple parabola (u-shape) function. It is a minimization objective function with an optima at -5.0. 1 2 3 WebTo demonstrate the minimization function, consider the problem of minimizing the Rosenbrock function of N variables: f(x) = N − 1 ∑ i = 1100(xi + 1 − x2i)2 + (1 − xi)2. The minimum value of this function is 0 which is achieved when xi = 1.
