WebThe method is repeated until we reach convergence. Note that in every iteration step, we now have to calculate only one function value, namely the value at the new point. For applying Golden-Search, we needed two function values in every iteration step. There also is a multidimensional extension of Brent’s method called Powell’s algorithm.
