Aug 16, 2013 at 16:26 | comment | added | usul | @Tino, ok, but if you are visiting $o(n)$ vertices and making $o(n)$ modifications (where $n$ is the number of vertices), it still seems very unlikely to me. | |
Aug 16, 2013 at 5:37 | comment | added | tuna | @usul: Remember that we can modify the graph locally, for example by deleting vertices we've visited. | |
Aug 16, 2013 at 1:39 | comment | added | usul | I'd guess that what you're asking is too difficult, unless we have a DAG. One intuition is that, if we cannot remember which vertices we've visited, then it will be difficult to distinguish between a small cycle and a very long line. | |
Aug 16, 2013 at 0:33 | comment | added | tuna | @Anton: I guess those are local modifications! But I'm looking for a method that will work when $G$ is too big to do, say, a number of operations as large as the number of vertices of $G$. | |

Aug 16, 2013 at 0:21 | comment | added | Anton Petrunin | Move from $v_0$ to $v_1$, remove $v_0$ and connect all the vertices which were connected to $v_0$ by edges; move from $v_1$ to $v_2$ and so on as far as you can walk. The number of steps gives you the number of vertices in a connected graph. | |
