It is not vertex cover but an edge covering we are interested in. Sorry I have been out of touch with graphs for quite some time. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Algorithm Geeks group. To post to

In graph theoretical terms the problem is to find a minimal (or a reasonably sized) vertex cover of a graph using complete multipartite graphs. bullockbefriending bard wrote: Any pointers much appreciated - I simply don't have the background or experience to be able to visualise what this

I think this one might have some optimal substructure, though it's not exactly clear what that may be. I'll give it some thought. On Dec 1, 6:26 am, smartdude [EMAIL PROTECTED] wrote: Reading about hamming distance and clustering methods might help. bullockbefriending bard wrote: A single

Thanks. I'm going to try to see what happens if I throw my data at py-cluster with some kind of nearness metric based initially upon Hamming distance - perhaps later can include bet size in this and kill two birds with one stone. Still going to be a lot of computational work to then group

Any pointers much appreciated - I simply don't have the background or experience to be able to visualise what this might be. I take it as a given that the problem is NP-hard at the very least and that there is no alternative but to go at it with some kind of greedy heuristic - and any way of
