It won't work; the methods that compare() use are all designed for
community structures where each node is a member of exactly one community.
There are alternative methods for comparing overlapping community
structures, but you'll have to implement these on your own.
Also if i have a graph with 6 nodes and community is #1 - { 1-2-3 } #2 -

The methods that compare() implement are not sensitive to the labeling of
the communities -- they will work just fine. (You can try it yourself -- in
your particular example, the two community structures will be considered
identical).
