Euler Tours in Hypergraphs
An Euler tour that starts and ends at the same vertex is called an Euler tour . ... Note that an Euler trail is sometimes also called an Euler walk or Euler path ...

Tight Euler tours in uniform hypergraphs - computational aspects
A tight tour in H is a tight Euler tour if it contains all edges of H. We prove that the problem of deciding if a given 3-uniform hypergraph has a tight Euler ...
A graph is Eulerian if it admits an Euler tour. An Euler trail is a trail (i.e., edges are distinct, ends may not be the same) that includes ...
On Tours that contain all Edges of a Hypergraph
For hypergraphs in this class we give a sufficient condition for existence of an Euler tour and prove intractability (NP-completeness) of the ...
13.1: Euler Tours and Trails - Mathematics LibreTexts
A connected graph (or multigraph, with or without loops) has an Euler tour if and only if every vertex in the graph has even valency. Proof.
A linear time algorithm for finding an Euler walk in a strongly ...
In [8] we studied the problems of existence of Euler walks and tours in strongly connected k-uniform hypergraphs. A k-uniform hypergraph H is strongly connected ...

Finding Euler tours and Euler families in hypergraphs via edge cuts. An Euler tour of a hypergraph H is a closed walk that traverses each edge of H exactly once ...
On tours that contain all edges of a hypergraph
Keywords: uniform hypergraphs, Euler tours, Euler walks. 1 Introduction. In this paper we study some hypergraph generalization of the graph ...
This property is because an Eulerian path or cycle leaves a node the same number of times it enters the node. In a directed graph the exception are the start ...
Definition · Eulerian cycle, also called an · Eulerian circuit or · Euler tour, in an undirected graph is a cycle that uses each edge exactly once. If such a cycle ...

The following theorem shows that the only possible obstruction for a Eulerian tour is a vertex of odd degree. Theorem: A connected graph has a Eulerian tour if ...
An Euler Tour is a cycle of a graph that traverses every edge exactly once. We write ET(G) for the set of all Euler tours of a graph G. Definition 2.3. The ...
Euler's Formula, Proof 20: Euler Tours - UC Irvine
A planar graph G has an Euler tour if and only if the degree of every vertex in G is even. Given such a tour, let R denote the number of times the tour reaches ...
An Euler tour (or circuit) in a graph G is a closed walk that visits every edge exactly once. It is not so difficult to see that this implies that all ...
