Abstract -
The Rational Search algorithm is a searching algorithm used to search for a particular element in an array. The array should be sorted in ascending order for using the algorithm. The Rational Search algorithm works in a similar manner as a human would search a word in a dictionary by directly jumping in the part where there is a high chance of finding the required item. It outperforms linear search as well as binary search when the data items in the array are approximately uniformly distributed, that is, the difference between any two adjacent elements are approximately the same for any other two adjacent elements in the array. Otherwise its performance is equivalent to a linear search algorithm.
