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.

WebI think there is a difference objective. Binary search is using for searching a specific value/item in a sorted data. On the other hand, Golden section search is using for searching extremum value in a function or a graph.
