WebFormula for Golden Section Search Method: X1 = Xu -C(Xu - X;) and X2 = x;+ C(Xu – X;) Where C = (–1715. 2-) = 0.61803 If f(x1) = f(x2), the sub-interval where the minimum occurs is [xx, xz], then update X, with X2 for next iteration, i.e., limit the working window by moving Xx to Xz. If f(x1) > f(x2), the sub-interval where the minimum ... 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 … See more The discussion here is posed in terms of searching for a minimum (searching for a maximum is similar) of a unimodal function. Unlike finding a zero, where two function evaluations with opposite sign are sufficient to bracket … See more Note! The examples here describe an algorithm that is for finding the minimum of a function. For maximum, the comparison operators need to … See more A very similar algorithm can also be used to find the extremum (minimum or maximum) of a sequence of values that has a single local minimum or local maximum. In order to approximate the probe positions of golden section search while probing only integer … See more From the diagram above, it is seen that the new search interval will be either between $${\displaystyle x_{1}}$$ and $${\displaystyle x_{4}}$$ with a length of a + c, or between See more Any number of termination conditions may be applied, depending upon the application. The interval ΔX = X4 − X1 is a measure of the absolute error in the estimation of the … See more • Ternary search • Brent's method • Binary search See more
