The 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 one of them. If the only extremum on the interval is on a boundary of the interval, it will converge to that boundary point. The method oper… WebFeb 24, 2016 · The golden section search reduces the interval known to contain the minimum by a fixed factor each iteration. You don't need the function to answer. I think I'm right in saying given [ a, b] I can evaluate [ a 1, b 1] where a 1 = a + r ( b − a) and b 1 = a + ( 1 − r) ( b − a) and take b 1 as part of the new interval [ a, b 1] hence ...
