迪杰斯特拉算法与prim算法的相似性

迪杰斯特拉算法和Prim算法在寻找路径时都是逐点添加，并且添加后需要重新更新路径，这是它们的相似之处。两种算法都可以用于从连通图中找出最小生成树或最短路径。然而，它们之间也有一些区别。迪杰斯特拉算法通过计算每个节点到起始节点的最短路径来构建最小生成树或找出最短路径，而Prim算法则是通过挨个添加节点来逐步构建最小生成树。此外，Kruskal算法在效率上要比Prim算法快，因为Kruskal只需要对权重边做一次排序，而Prim算法则需要做多次排序。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
