Minimum spanning tree prim algorithm

WebLet's find a minimum spanning tree from the above graph using Prim's algorithm. Step 1: Select a random vertex to start then add it to the MST component, in this case, we will select vertex 0. Step 2: Then choose the minimum cost weight from node 0, in this case, we have two edges, 0-1 and 0-2, here edge 0-1 edge has the minimum cost. Web演算法步驟如下： 首先，初始化所有vertex的資料項目，見圖一 (b)： predecessor [] 設成 − 1 ，表示vertex沒有predecessor。 key [] 設成「無限大」，表示所有vertex都沒有辦法經由與其餘vertex相連之edge抵達。 visited [] 設成 0 ，表示MST裡面還沒有vertex。 (程式範例中， visited [] 的資料型態是用 bool ，因此設為 false) 圖一 (b)。 初始化之後，選定其中一 …
