(PAT 1122) Hamiltonian Cycle (哈密顿图) The "Hamilton cycle problem" is to find a simple cycle that contains every vertex in a graph. Such a cycle is called a "Hamiltonian cycle". In this problem, you are supposed to tell if a given cycle is a Hamiltonian cycle. Input Specification: ...

The hamiltonian cycle for the cases m = 10 and m = 11 are shown in the Figures 2.2 and 2.3 respectively. Cyclic Hamiltonian graphs If the degree sum of any two nonadjacent vertices is at least n, then G has a Hamiltonian Cycle. An algorithm to detect cycle in an undirected graph In ...
After an original Hamiltonian cycle is found, we insert the remaining points to it. Finally, we present an O((n2+m)nlogm) time algorithm (n is the number of points in X and m is the number of P's vertices) to report a Hamiltonian cycle if it exists or report that no such cycle...

Higher number of edges creates more possibilities to check...
This paper gives the recursive algorithm for Hamiltonian cycle and TSP (travelling salesman problem) based on the backtracking approach. If at any stage it is detected that the particular input or combination will not lead to an optimal solution than we can discard and a new input can be ...
