WebIt uses analog of the bisection method to decrease the bracketed interval. It is usually preferable to use the Brent method. Method Bounded can perform bounded … WebThe golden-section search is a technique for finding an extremum (minimum or maximum) of a function inside a specified interval. For a strictly unimodal function with an extremum inside the interval, it will find that extremum, while for an interval containing multiple extrema (possibly including the interval boundaries), it will converge to ...
