| Nov 21, 2016 at 5:31 | comment | added | user94040 | @PatDevlin You are right in only vertex set matters. I thought it will be easy to visualize in these terms. I see your point on randomness. I just felt there may be a possibility. | |
| Nov 21, 2016 at 5:25 | comment | added | Pat Devlin | A few points are unclear to me. For instance, what does the graph structure have to do with anything? It seems to me that it's not important at all, right? Everything seems to be about vertex sets, so why not just state it all in terms of sets? [and this problem doesn't strike me as one where the probabilistic method would help. It sounds like you're insisting on something far from random. But I admit I might not be understanding you correctly, since I'm not quite sure what you mean.] | |
