Golden section method formula
WebThe Golden Section Search method f(x) is continuous over [a,b] and f(x) is "unimodal" over [a,b], meaning that f(x) has only one minimum in [a,b]. WebNotice, however, that this formula is happy jumping to a parabolic maximum as to a minimum. To rely exclusively on the formula is not good practice. In practice one wishes a scheme that operates on something guaranteed to succeed, like the golden section method, combined with a parabolic approximation when one
