Difference between Hamiltonian path and ST

I was reading up algorithms for finding the minimum spanning tree(in case of weighted graphs) and for finding if a graph has a hamiltonian path(which depends on the presence of a hamiltonian cycle). I[详细]

GCJ - Hamiltonian Cycles

Code jam problem is the following: You are given a complete undirected graph with N nodes and K \"forbidden\" edges. N <= 300, K <= 15. Find the number of Hamiltonian cycles in the graph that d[详细]

Enumerate *all* hamiltonian paths

I know this has been asked before, but I did not find its answer in any of the posts. Can someone please suggest me an algorithm which enumerates ALL Hamiltonian paths in a graph?[详细]

Finding the hamiltonian path in a directed cyclic graph

i want to know if there is an algorithm to find the longest cyclic path in a directed weighted graph (i think this i a problem of finding the largest Hamiltonian sub-graph).[详细]

How do I find the number of Hamiltonian cycles that do not use "forbidden" edges?

This question actually rephrases that one. The code jam problem is the following: You are given a complete undirected graph with N nodes and K \"forbidden\" edges. N <= 300, K <= 15. Find the n[详细]

Problem in finding Hamiltonian circuit for TSP problem

Hi there Im working on a project which needs to solve the TSP problem. The thing i need here is that how i can find the Hamiltonian circuits in the graph. In fact I know how to do this in the real wor[详细]

Is there an algorithm for computing permutation of distances?

This is related to travelling salesman problem. First all permutations need to be generated and then the destination (same as origin) attached. I.e.:[详细]

Finding Hamiltonian cycles in cubic planar graphs

I have relatively small (40-80 nodes) cubic (3-regular) planar graphs, and I have to decide their Hamiltonicity. I am aware of the fact that this task is 开发者_运维问答NP-complete, but I hope for asy[详细]
