"WebNov 29, 2014 · 3 Answers. You cant use Floyd Warshall with adjacency list because when it works, it makes new edges. First, your graph has 2 Edges ( 1-2, 2-3 ). So you initialize the adjacency matrix : And when FW works, edge 1-3 wil be added because adj [1] [2] + adj [2] [3] < adj [1] [3] => adj [1] [3] = 2 ( means have edge between 1 and 3 ); I dont know ...
