WebJan 13, 2024 · A Hamiltonian path is a path that passes through every vertex exactly once (NOT every edge). If it ends at the initial vertex then it is a Hamiltonian cycle. In an Euler path you might pass through a vertex more than once. In a Hamiltonian path you may not pass through all edges.

Figure 6.4. 1: Examples of Hamilton Paths Not all graphs have a Hamilton circuit or path. There is no way to tell just by looking at a graph if it has a Hamilton circuit or path like you can with an Euler circuit or path.
In the mathematical field of graph theory, a Hamiltonian path (or traceable path) is a path in an undirected or directed graph that visits each vertex exactly once.

WebAny algorithm that can solve the $k$-Hamiltonian path problem must, in particular, be able to solve the case $k=1$, which is just an ordinary Hamiltonian path. We can obviously verify a claimed $k$-Hamiltonian path in polynomial time, so the problem remains in NP. Therefore, $k$-Hamiltonian path is NP -complete. Share Cite Improve this answer
Web2. Easy Version: A Hamiltonian path is a simple path of length n − 1, i.e., it contains every vertex. Example: The tournament of Handout#6 has the Hamiltonian path a,b,c,d,e.
