Euler Tour of Tree - GeeksforGeeks

https://www.geeksforgeeks.org/euler-tour-tree/

Mar 30, 2018 · Euler tour is defined as a way of traversing tree such that each vertex is added to the tour when we visit it (either moving down from parent vertex or returning from child vertex). We start from root and reach back to root after visiting all vertices. It requires exactly 2*N-1 vertices to store Euler tour. Approach: We will run DFS(Depth first search) algorithm on Tree as:2/5

Eulerian path and circuit for undirected graph - GeeksforGeeks

https://www.geeksforgeeks.org/eulerian-path-and-circuit/

Jun 13, 2013 · A graph is called Eulerian if it has an Eulerian Cycle and called Semi-Eulerian if it has an Eulerian Path. The problem seems similar to Hamiltonian Path which is NP complete problem for a general graph. Fortunately, we can find whether a given graph has a Eulerian …3.3/5

https://github.com/keerthibs/Eulerian-Tour

A graph G is called Eulerian if it is connected and the degree of every vertex is an even number. It is known that such graphs aways have a tour (a cycle that may not be simple) that goes through every edge of the graph exactly once. Such a tour (sometimes called a circuit) is called an Euler tour. If the graph is connected, and it has exactly 2 nodes of odd degree, then it has an Euler Path ...

What is a Euler or Eulerian tour?

https://iq.opengenus.org/what-is-a-euler-or-eulerian-tour/

An Euler tour or Eulerian tour in an undirected graph is a tour/ path that traverses each edge of the graph exactly once. Graphs that have an Euler tour are called Eulerian graphs. Necessary and sufficient conditions. An undirected graph has a closed Euler tour if and only if …

Eulerian path - Wikipedia

https://en.wikipedia.org/wiki/Eulerian_path

Eulerian trails are used in bioinformatics to reconstruct the DNA sequence from its fragments. They are also used in CMOS circuit design to find an optimal logic gate ordering. There are some algorithms for processing trees that rely on an Euler tour of the tree (where each edge is treated as a pair of arcs). The de Bruijn sequences can be constructed as Eulerian trails of de Bruijn graphs.
