Adjacent Vertices Fault Tolerance Hamiltonian Laceability of Star Graphs
Let Sn be an n-dimensional Star graph. In this paper, we show that Sn − F is Hamiltonian laceable where F is the set of f ≤ (n − 4) pairs of adjacent faulty vertices, Sn − F is Hamiltonian where F is the set of f ≤ (n − 3) pairs of adjacent faulty vertices. We also show that Sn − F is hyper-Hamiltonian laceable where F is the set of f ≤ (n − 4) pairs of adjacent faulty vertices. Applying these ...
متن کاملOn the Hamiltonian Laceability of Honeycomb Toroidal Graphs
The Honeycomb toroidal graph is a highly symmetric, vertex-transitive, bipartite graph which has been investigated for certain properties including pan-cyclicity and Hamilton laceability. The main focus of this project was to construct generalised methods for finding Hamilton paths and thus provide a proof of Hamilton laceability for this graph. The resulting proof was successful for a subset o...
متن کاملHamiltonian-connectivity and strongly Hamiltonian-laceability of folded hypercubes
In this paper, we analyze a hypercube-like structure, called the folded hypercube, which is basically a standard hypercube with some extra links established between its nodes. We first show that the n-dimensional folded hypercube is bipartite when n is odd.We also show that the n-dimensional folded hypercube is strongly Hamiltonian-laceable when n is odd, and is Hamiltonian-connected when n = 1...
متن کاملFault-tolerant hamiltonian laceability of hypercubes
It is known that every hypercube Qn is a bipartite graph. Assume that n 2 and F is a subset of edges with |F | n− 2. We prove that there exists a hamiltonian path in Qn − F between any two vertices of different partite sets. Moreover, there exists a path of length 2n − 2 between any two vertices of the same partite set. Assume that n 3 and F is a subset of edges with |F | n− 3. We prove that th...
متن کاملPaired 2-disjoint path covers and strongly Hamiltonian laceability of bipartite hypercube-like graphs
A paired many-to-many k-disjoint path cover (paired k-DPC for short) of a graph is a set of k vertex-disjoint paths joining k distinct source-sink pairs that altogether cover every vertex of the graph. We consider the problem of constructing paired 2-DPC’s in an m-dimensional bipartite HL-graph, Xm, and its application in finding the longest possible paths. It is proved that every Xm, m ≥ 4, ha...
