Dec 19, 2023 · Interpolation search works better than Binary Search for a Sorted and Uniformly Distributed array. Binary Search goes to the middle element to check irrespective of search-key. On the other hand, Interpolation Search may go to different locations according to search-key.

Although linear and binary searching produces the same overall results, linear search is best used when the data is not in order, or for smaller lists.
Mar 21, 2014 · My list of reasons for choosing a linear search over a binary search are as follows:
- Overview
- Linear Search
- Binary Search
- Comparison
- Conclusion
Search problems are some of the most common in programming, and there are many ways to solve them. Two of these ways are Linear Search and Binary Search. In this tutorial, we’re going to explain the two methods and provide a comparison between them.
2.1. Theoretical Idea
Linear Search scans one item at a time and can be used to solve any kind of search problem.
2.2. Linear Search in an Array
We can use Linear Search to look for a value inside an array. We iterate over all the elements of the array and stop when the searched value is found. However, note that no conditions are needed to use this kind of search. Let’s take a look at the implementation of the discussed algorithm: The total time complexity of the above algorithm is , where is the total number of elements in the array.
2.3. Linear Search for an Answer
Let’s take an example to explain this idea. Suppose we want to make bottles of fruit juice of determined sizes. We have some amount of money, and there’s a shop nearby that sells fruits for fixed prices. We want to know the maximum number of bottles we can make. To simplify the problem, we’ll assume that there’s a function that takes the number of bottles as input. This function returns true if the money we have is enough to make that number of bottles, and returns falseotherwise. Then, we’ll...
3.1. Theoretical Idea
Binary Search’s main idea is to split the search range in half. Then, we check the middle value. Based on the middle value, we decide whether to continue our search inside the left or the right part.
3.2. Binary Search in an Array
Unlike Linear Search, the condition to use Binary Search is that the array should be sorted. Suppose you want to look for a value in an array . First, we define the lowest value of the searched range to be 1, which is the smallest index inside the array. Also, we define the highest value to be , where is the number of elements in the array, which is the largest possible index inside the array. After that, we perform multiple steps. In each step, we take the middle element and check if it’s th...
3.3. Binary Search for an Answer
We can’t always use Binary Search to look for an answer to a problem because there’s a condition that should be met. The condition states that the range in which we search for a specific value must have exactly one accepted continuous part and exactly one unaccepted continuous part. Let’s take the same example as in Linear Search for an answer and apply binary search on the range of values. Firstly, we assume that we have the same function we mentioned earlier. Secondly, we define the lowest...
Taking a look at the table, we see the main differences between Binary Search and Linear search. In other words, it’s best to solve a problem with Binary Search if possible because of its lower complexity.
In this tutorial, we explained the Linear Search and Binary Search theoretically. Then, we talked about search in an array and search for the answer to a problem. After that, we saw how to solve each problem using the two search methods. Finally, we presented a basic comparison between the two approaches.
Apr 3, 2023 · Differences Between Binary Search and Linear Search. Prerequisites: Binary search requires the input array to be sorted, whereas linear search can work on both sorted and unsorted arrays. Efficiency: Binary search is more efficient than linear search, especially for large datasets.
Aug 25, 2017 · Binary search is surprisingly good to stand against linear search, given that it fully utilizes conditional move instructions instead of branches. In my opinion, there is no reason to prefer linear search over binary search, better make sure that your compiler does not generate branches for the binary search.

Jan 11, 2022 · Approach for Binary Search. Compare the target element with the middle element of the array. If the target element is greater than the middle element, then the search continues in the right half. Else if the target element is less than the middle value, the search continues in the left half.
