單源點最短路徑算法的設計與實現 算法 Shortest-PATHS求出了v0至其它各結點的最短路徑,但是沒有給出這些最短路徑。補充該算法,使新算法在找出這些最短路徑長度的同時,也能求出路徑上的結點序列。

Floyd-Warshall算法描述 1)適用范圍: a)APSP(All Pairs Shortest Paths) b)稠密圖效果最佳 c)邊權可正可負 2)算法描述: a)初始化:dis[u,v]=w[u,v] b)For k:=1 to n For i:=1 to n For j:=1 to n If dis[i,j]>dis[i,k]+dis[k,j] Then Dis[I,j]:=dis[I,k]+dis[k,j] c)算法結束:dis即為所有點對的最短路徑矩陣 3)算法小結:此算法簡單有效,由于三重循環結構緊湊,對于稠密圖,效率要高于執行|V|次Dijkstra算法。時間復雜度O(n^3)。 考慮下列變形:如(I,j)∈E則dis[I,j]初始為1,else初始為0,這樣的Floyd算法最后的最短路徑矩陣即成為一個判斷I,j是否有通路的矩陣。更簡單的,我們可以把dis設成boolean類型,則每次可以用“dis[I,j]:=dis[I,j]or(dis[I,k]and dis[k,j])”來代替算法描述中的藍色部分,可以更直觀地得到I,j的連通情況。

Shortest Paths with Multiplicative Cost. In a given undirected graph, the path cost is measured as a product of all the edges in the path. The weights are rational numbers (e.g., 0.25, 0.75, 3.75 etc) or integers (2, 3). There are no negative edges. Given such a graph as input, you are to output the shortest path between any two given vertices. Input is the adjacency matrix and the two vertices. You must output the path.

There are many algorithms that can be applied to graphs. Many of these are actually used in the real world, such as Dijkstra’s algorithm to find shortest paths. We will discuss a few here.

In some graphs, the shortest path is given by optimizing two different metrics: the sum of weights of the edges and the number of edges. For example: if two paths with equal cost exist then, the path with the least number of edges is chosen as the shortest path. Given this metric, you have find out the shortest path between a given pair of vertices in the input graph. The output should be the number of edges on the path, the cost of the shortest path, and the path itself. Input is the adjacency matrix and the two vertices.
