Overview

Fibonacci lookup is similar to binary lookup. The difference is that a binary lookup is compared at the midpoint of the upper limit of the lookup range, while a Fibonacci lookup is performed on a Fibonacci shard of the upper limit of the lookup range.

Analysis

The Fibonacci search is divided based on the Fibonacci series based on the binary search. Find a number in the Fibonacci series that is equal to or greater than the number of elements in the query table F [n], and extend the original query table to the length F [n] (if you want to add elements, then, repeat the last element until F [n] elements are satisfied. Then, perform the Fibonacci splitting, that is, F [n] elements are divided into the first half of F [n-1] elements, the second half of F [N-2] elements, find the element to be searched in that Part and recursion, until it is found.

The advantage of the Fibonacci search is that when determining the next comparison element, it can be calculated only by adding or subtracting, which is less time than the division of the binary search.
