在无向图的邻接多重表中，所需存储空间与表示无向图的邻接表相同。 * w( l, c- t3 w9 y% j在无向图的应用中，如果更加关注图的顶点，那么邻接表是不错的选择，但如果我们更关注边的操作，比如对已访问过的边做标记，删除某一条边等操作，那就意味着需要找到这条边的两个边表结点进行操作，若要删除某条边，需要对邻接表结构中相关的两个结点进行删除，显然这是比较繁琐的。, B% i% B v+ w4 X) b/ G! h
为了提高在无向图中操作顶点的效率，又有了邻接多重表的存储结构。邻接多重表与邻接表的区别在于，同一条边，在邻接多重表中要用两个结点表示，而在邻接表中只需要一个结点。此外，邻接多重表中增加了标志域用以标记该条边是否被搜索过，避免了同一条边的重复搜索。# b( \5 ^& x; O0 I: L7 `
