# Brute Force vs. Exhaustive Search: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Published on December 11, 2023

**Brute force is a straightforward approach to solving problems by trying all possible solutions. Exhaustive search methodically examines all possible solutions to find the best one.**

## Key Differences

Brute force involves solving a problem by trying all possible combinations or permutations until the correct solution is found. It’s a simple, yet resource-intensive method. Exhaustive search is a more systematic approach, reviewing all possible options in an orderly manner to find the optimal solution. It is thorough but can be time-consuming.

In a brute force method, there is no regard for efficiency or cleverness; it relies on sheer computational power and can be used for a variety of problems. Exhaustive search, while similar in trying all possibilities, often follows a more structured approach, potentially categorizing or ordering the search process to be more methodical.

Brute force is often used in contexts where the number of possibilities is not prohibitively large, or where there is no better algorithm available. It's about trial and error. Exhaustive search, on the other hand, assumes that the total number of possibilities is manageable and systematically works through them, possibly employing strategies to reduce the search space.

A brute force approach can be seen as less sophisticated, often used when simplicity is more important than efficiency. It doesn’t require prior knowledge about the problem. Exhaustive search may require some understanding of the problem domain to structure the search effectively, aiming for a more efficient exploration of all possibilities.

Brute force can be less effective for complex problems with a vast number of possible solutions due to time and resource constraints. Exhaustive search is also constrained by the number of possibilities but attempts to be more organized and efficient in exploring these possibilities, sometimes employing optimization strategies.
