2023年11月6日 · 这篇题解中也只能找出任意环。 每次会把环上的后继加进去，所以刚好每个点都被加入一次。 hn[1] 是终点 x，然后是它的第一个邻居。 就是找到环上第一个与 x 直接相连的点，然后调整环为这个环。 反证容易证明这个环是极小的。 他就是按照两条红线（任意一个）的顺序，找到一个极小环。 所以其实直接dfs确实是找不到所有环的。 ins[u] = true; .

2023年6月27日 · 题目大意：给你一张 无向图，让你判断是否存在鱼图，若有则输出其组成边和“YES”，否则输出“NO”。 鱼图：如上图红线标记的. 思路： 我们通过 vector 数组 记录无向图，暴力枚举每个点，找到度数大于等于4的点设为监测点，然后标记他的所有与他直接相连的点，每次dfs这个相连的点，并且设置一个fnei（第一个邻居）作为参照，当now这个点已经向下dfs搜索到了当前所枚举的监测点的另一个邻居说明当前监测点存在一个环（自己和两个邻居相连，dfs出 …

2023年5月5日 · 本题可以使用深度优先搜索算法。 首先可以尝试寻找那个度数不小于 4的特殊结点，确定该结点后，用深度优先搜索找该点所在的环。 具体地，开始时选择“特殊结点”的邻接点中随便一个结点开始找环，搜索中对于每一个点，遍历除了它的前驱的所有临接点。 若再次搜到起始点（即“特殊结点”），就把环上所有边记下来返回。 最后输出这些记下来的边，然后从连接特殊结点的其他边中随便选 2条出来输出即可完成要求。 如果所有的度数不小于 4的结点都不满足条 …

The graphs, often constructed from data in several FishBase tables are not always straightforward to interpret, as was noted in a review of FishBase (Wootton 1997). Therefore, we introduced boxes (see Box 2) as devices for explaining the theory behind a given graph, and the related table entries, and to explain how the graph was built, and/or ...
