Floyd Warshall algorithm with its Pseudo Code

WebFloyd-Warshall is a Dynamic-Programming algorithm. Let's look at an example. We're going to apply Floyd-Warshall's algorithm on this graph: (opens new window) First thing we do is, we take two 2D matrices. These are adjacency matrices (opens new window). The size of the matrices is going to be the total number of vertices. ... The pseudo-code ...

"The Floyd–Warshall algorithm can be used to solve the following problems, among others: • Shortest paths in directed graphs (Floyd's algorithm). • Transitive closure of directed graphs (Warshall's algorithm). In Warshall's original formulation of the algorithm, the graph is unweighted and represented by a Boolean adjacency matrix. Then the addition operation is replaced by logical conjunction (AND) and the minimum operation by logical disjunction (OR). " - Floyd warshall pseudocode
