Splet26. avg. 1996 · Consider computing a Hamiltonian path 77-4 of shortest length from ao to 04, and assume without loss of generality that the line passing through ao and u4 is horizontal. Partition the set of points S into two sequences: an upper sequence U = 0,1-1, 0,1-2, , a-h and a lower sequence L = ao,a\,... ,ak-\ (see Fig. 1 ). 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. A Hamiltonian cycle (or Hamiltonian circuit) is a cycle that visits each vertex exactly once. A Hamiltonian path that starts and ends at adjacent vertices can be completed by adding one more edge to form a Hamiltonian cycle, and remo…

SpletThe 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.
