Brent's method minimization

Webtion technique is the method ofsteepest descent. The main idea is to change the current parameter estimates in the direction ofthe largest decrease inf. For a linear func tion,. this direction is the direction ofthe negative ofits gr~dl~nt. v.:e find ~eminimum value of the function along this direction and Iterate the procedure until the function Webmethod to solve for the optimal choice of x 1 and x2. Hence, we need a minimization routine. When using a minimization algorithm with an equality constraint, it is always …

The reason is that the SD method easily winds up in a zig-zag pattern which does not move towards the minimum efficiently as in WebBrent's method [ Br02] is effectively a safeguarded secant method that always keeps a point where the function is positive and one where it is negative, so that the root is always bracketed. At any given step, a choice is made between an interpolated (secant) step and a bisection in such a way that eventual convergence is guaranteed.
