Hamiltonian paths in L-shaped grid graphs

چکیده
Grid graphs are subgraphs of the infinite 2-dimensional integer grid. The Hamiltonian path problem for general grid graphs is a well-known NP-complete problem. In this paper, we present necessary and sufficient conditions for the existence of a Hamiltonian path between two given vertices in L−shaped grid graphs. We also show that a Hamiltonian path between two given vertices of a L−shaped grid graph can be computed in linear time. c © 2011 Published by Elsevier Ltd.

Hamiltonian Paths in C-shaped Grid Graphs
One of the well-known NP-complete problems in graph theory is the Hamiltonian path problem; i.e., finding a simple path in the graph such that every vertex visits exactly once [5]. The two-dimensional integer grid G is an infinite undirected graph in which vertices are all points of the plane with integer coordinates and two vertices are connected by an edge if and only if the Euclidean distanc...

In this paper, we give the necessary and sufficient conditions for the existence of Hamiltonian paths in L−alphabet and C−alphabet grid graphs. We also present a linear-time algorithm for finding Hamiltonian paths in these graphs.
متن کاملHamiltonian Paths in Some Classes of Grid Graphs
The Hamiltonian path problem for general grid graphs is known to be NP-complete. In this paper, we give necessary and sufficient conditions for the existence of Hamiltonian paths in L-alphabet, C-alphabet, F-alphabet, and E-alphabet grid graphs. We also present linear-time algorithms for finding Hamiltonian paths in these graphs.
متن کاملSqueeze-free Hamiltonian Paths in Grid Graphs
Motivated by multi-robot construction systems, we introduce the problem of finding squeeze-free Hamiltonian paths in grid graphs. A Hamiltonian path is squeeze-free if it does not pass between two previously visited vertices lying on opposite sides. We determine necessary and sufficient conditions for the existence of squeeze-free Hamiltonian paths in staircase grid graphs. Our proofs are const...
متن کاملThe Hamiltonian Connected Property of Some Shaped Supergrid Graphs
A Hamiltonian path (cycle) of a graph is a simple path (cycle) which visits each vertex of the graph exactly once. The Hamiltonian path (cycle) problem is to determine whether a graph contains a Hamiltonian path (cycle). A graph is called Hamiltonian connected if there exists a Hamiltonian path between any two distinct vertices. Supergrid graphs were first introduced by us and include grid grap...
