WebMar 21, 2024 · We have discussed Dijkstra’s algorithm and its implementation for adjacency matrix representation of graphs. The time complexity for the matrix representation is O (V^2). In this post, O (ELogV) algorithm for adjacency list representation is discussed. As discussed in the previous post, in Dijkstra’s algorithm, … WebFor example, Dijkstra 1 is more efficient than Floyd 2 if P N and Table 3.7: Performance of four parallel shortest-path algorithms. In addition to these factors, we must consider the fact that algorithms Dijkstra 1 and Dijkstra 2 replicate the graph P and P/N times, respectively. This replication may compromise the scalability of these algorithms.
