Key Points

Dijkstra's Algorithm: This algorithm is used for finding the shortest path between nodes in a graph. It is widely applied in GPS route finding systems to compute the most efficient routes.
Huffman Coding: This is a lossless data compression algorithm that assigns variable-length codes to input characters. It is commonly used in data compression techniques to reduce file sizes.
KMP String Matching: The Knuth-Morris-Pratt (KMP) algorithm is an efficient method for pattern searching in strings. It is frequently used in text editor search functions for locating specific words or patterns in text documents.
Ford-Fulkerson: This algorithm computes the maximum flow in a flow network. It is highly utilized in network bandwidth optimization to maximize data flow in computer networks.
