The golden-section search is an efficient way to progressively reduce the interval locating the minimum. The key is to observe that regardless of how many points have been evaluated, the minimum lies within the interval defined by the two points adjacent to the point with the least value so far evaluated. See more 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, … See more Any number of termination conditions may be applied, depending upon the application. The interval ΔX = X4 − X1 is a measure of the … 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 be reversed. Iterative algorithm See more • Ternary search • Brent's method • Binary search 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 … 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 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.

4.2 Golden Section Search Method for Optimization using MATLAB
WebIn an earlier post, I introduced the golden section search method – a modification of the bisection method for numerical optimization that saves computation time by using the golden ratio to set its test points.. This post contains the R function that implements this method, the R functions that contain the 3 functions that were minimized by this … WebOutline: † Part I: one-dimensional unconstrained optimization – Analytical method – Newton’s method – Golden-section search method † Part II: multidimensional … city of hudsonville zoning
