10 Famous Algorithms in Computer Science

1. Dijkstra's Algorithm:

This algorithm is used to find the shortest path between two nodes in a graph. It is widely used in network routing protocols and transportation planning.

2. Depth-First Search (DFS) and Breadth-First Search (BFS):

These graph traversal algorithms are fundamental and widely used across various applications such as finding connected components, solving puzzles, and searching in trees and graphs.

3. Binary Search:

This efficient search algorithm is used to find a specific element in a sorted array. It has applications in searching and data retrieval.

4. QuickSort:

QuickSort is a widely used sorting algorithm known for its efficiency. It has an average-case time complexity of O(n log n) and is often faster in practice than other sorting algorithms.

5. MergeSort:

MergeSort is a divide-and-conquer sorting algorithm that guarantees a time complexity of O(n log n) in all cases. It is known for its stability and is used in many applications where a stable sorting order is required.

6. Bellman-Ford Algorithm:

This algorithm is used to find the shortest paths in a weighted directed graph, even when the graph contains negative weight edges. It is commonly used in network routing protocols.

7. Knapsack Problem Algorithms:

The Knapsack problem involves finding the optimal combination of items to include in a knapsack, given their values and weights. There are various algorithms to solve this problem, including dynamic programming and greedy algorithms.

8. Prim's Algorithm and Kruskal's Algorithm:

These algorithms are used to find the minimum spanning tree in a weighted graph. They have applications in network design, clustering, and optimization problems.

9. A* Search Algorithm:

A* is a popular pathfinding algorithm that combines elements of Dijkstra's algorithm and heuristics to find the shortest path between two nodes in a graph. It is commonly used in applications such as GPS navigation and robotics.

10. RSA Algorithm:

RSA is a widely used asymmetric encryption algorithm for secure communication. It is based on the difficulty of factoring large prime numbers and forms the basis of many secure communication protocols.
