WebDijkstra算法是贪心算法，是一个单源最短路算法，就是先记录下从起始点到各个点的距离，然后选择距离最小的结点，用这个最小距离加上选取的点和其他点一一比较，看看需 … WebExplanation: In Prim’s algorithm, the MST is constructed starting from a single vertex and adding in new edges to the MST that link the partial tree to a new vertex outside of the MST. And Dijkstra’s algorithm also rely on the similar approach of finding the next closest vertex. So, Prim’s algorithm resembles Dijkstra’s algorithm. pub crawl the rocks
