Does the graph have a Hamiltonian circuit or a Hamiltonian path ...
Feb 16, 2024 · Certain necessary conditions for a Hamiltonian circuit such as the graph being 2-connected, having zero pendants are met. Dirac's and Ore's theorem provide sufficient conditions, …
discrete mathematics - What is the difference between a Hamiltonian ...
Aug 18, 2020 · Hamiltonian path is a path in an undirected or directed graph that visits each vertex exactly once Hamiltonian cycle is a Hamiltonian path that is a cycle, and a cycle is closed trail in …
How many Hamiltonian circuits are there in a complete graph with n ...
A Hamiltonian circuit (or cycle) visits every vertex exactly once before returning to its starting point. An Eulerian circuit visits every edge exactly once in the graph before returning to the starting point.
Reduction from Hamiltonian cycle to Hamiltonian path
Oct 18, 2010 · I'm looking for an explanation on how reducing the Hamiltonian cycle problem to the Hamiltonian path's one (to proof that also the latter is NP-complete). I couldn't find any on the web, …
graph theory - If $deg (u)+deg (v) \ge n-1$ for $u$ and $v$ are non ...
Hamiltonian path is a path that contains all of the vertices of the graph. I know that if $deg (u)+deg (v) \ge n$ for every two non adjacent vertices $u$ and $v$ then the graph has Hamiltonian cycle and …
Are there any efficient ways to tell if a graph has a Hamiltonian circuit?
For example, consider this graph. What are some common methods for determining whether the graph has a Hamiltonian circuit? After trying to find one, I'd conclude that it doesn't, but I don't kno...
How many Hamiltonian cycles are there in a complete graph $K_n$ ($n ...
There are $\frac {n-1} {2}$ such consecutive pairs in the upper half of the circumference with $\frac {n-1} {2}$ edges connecting them each leading to unique edge disjoint Hamiltonian circuits.
Difference between Hamiltonian and Lagrangian Mechanics
Nov 16, 2017 · Hello, I am trying to "integrate into my understanding" the difference between Hamiltonian and Lagrangian mechanics. In a nutshell: If Lagrange did all the work and formulated L …
Is any tree a Hamiltonian Graph - Mathematics Stack Exchange
Sep 23, 2018 · Hamiltonian path is a graph where every vertex is visited exactly once. And a tree can be anything, like a BST. I think that this answer is no because in a BST, it could find an element before …
