Euler Tours in Hypergraphs


Euler Tours - Oscar Levin

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 ...

Covering hypergraphs are Eulerian - Wiley Online Library

1‐overlap cycle, covering hypergraph, Euler family, Euler tour, ... Initial results for. Euler tours in Steiner triple and quadruple systems ...

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 ...

Section 3.3. Euler Tours

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 ...

Keywords: uniform hypergraphs, Euler tours, Euler walks. 1 Introduction. In this paper we study some hypergraph generalization of the graph ...

Eulerian Tours - USACO Guide

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 ...

Eulerian path - Wikipedia

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 ...

Graphs and Eulerian tours

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 ...

Euler Tours on the Grid

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 ...

Euler tour Hamilton cycles

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 ...
