图G的欧拉回路(Euler circuit)指的是遍历G中每一条边的简单回路(simple circuit), 这样的轨迹称为欧拉环游(Euler tour) 图G的欧拉路径(Euler path)指的是遍历G中每一条边的简单路径(simple path), 这样的轨迹称为欧拉轨迹(Euler trail) 有欧拉回路的图称为欧拉图,无欧拉回路但是有欧拉路径的图称为半
An Eulerian graph is a special type of graph that contains a path that traverses every edge exactly once. It starts at one vertex (the “initial vertex”), ends at another (the “terminal vertex”), and visits all edges without any repetition. On the other hand, an Euler Circuit is a...
D is degree 3, and E is degree 1. This graph contains two vertices with odd degree (D and E) and three vertices with even degree (A, B, and C), so Euler’s theorems tell us this graph has an Euler path, but not an Euler circuit. ...

If the graph has two odd vertices, then it has an Euler path. If it has more than two odd vertices, it has neither an Euler circuit nor an Euler path. If it is calculated that the graph has an odd number of odd vertices, a mistake has been made. What are Euler's theorems? This...
UVa 10735 (混合图的欧拉回路) Euler Circuit 题意: 给出一个图,有的边是有向边,有的是无向边。试找出一条欧拉回路。 分析: 按照往常的思维,遇到混合图,我们一般会把无向边拆成两条方向相反的有向边。 但是在这里却行不通了,因为拆成两条有向边的话,就表示这个边能“在两个相反方向各经过一次”。

UVA 10735 Euler Circuit 混合图的欧拉回路(最大流,fluery算法),题意:给一个图,图中有部分是向边,部分是无向边,要求判断是否存在欧拉回路,若存在,输出路径。分析:欧拉回路的定义是,从某个点出发,每条边经过一次之后恰好回到出发点。无向边同样只能走一次,只是
This Java program is Implement Euler Circuit Problem.In graph theory, an Eulerian trail (or Eulerian path) is a trail in a graph which visits every edge exactly once. Similarly, an Eulerian circuit or Eulerian cycle is an Eulerian trail which starts and ends on the same vertex. Here is ...
