Explaining the Floyd-Warshall Algorithm with Examples The Floyd-Warshall algorithm is a dynamic programming algorithm used to find the shortest path between all pairs of vertices in a weighted directed graph. Developed by Robert Floyd and Stephen Warshall in 1962, this algorithm efficiently solves the All-Pairs Shortest Path (APSP) problem, which has various applications in network routing, traffic optimization, and path planning. This article will provide a detailed explanation of the Floyd-Warshall algorithm , along with a step-by-step example and a corresponding code implementation. Understanding the Floyd-Warshall Algorithm: The Floyd-Warshall algorithm operates by maintaining a two-dimensional matrix, often referred to as the "distance matrix" or "DP matrix." This matrix stores the shortest distance between each pair of vertices in the graph. Initially, the matrix is populated with the direct distances between the vertices. However, if there is no direct edge...
