"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 … Se mer 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 a … Se mer 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 1. Specify the function to be minimized, f(x), the interval to be … Se mer • Ternary search • Brent's method • Binary search Se mer 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 Se mer 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 … Se mer 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.
