Floyd Warshall Algorithm - Coding Ninjas

WebThe Floyd-Warshall algorithm in C is a graph algorithm that finds the shortest path between two vertices in a graph in a weighted graph with positive or negative edge weights but without negative cycles. The algorithm is named after the British mathematician Floyd Warshall. The algorithm is also known as the all-pairs shortest path algorithm. Web1 The reason is that the numbers d i k and d k j do not change when computing matrix D k; distances either starting or ending in k cannot be improved by looking for a path that travels via k (or equivalently, d k k = 0 ). The right-hand side of the instructions of the algorithm only involve these numbers on the k -th row and column. lithium in short supply
