v.net.connectivity computes vertex connectivity between two sets,
i.e. the minimum number of vertices whose removal would separate two
given sets.
NOTES
Two sets (set1 and set2) are specified by respective
layer, where and cats parameters. Similarly to
v.net.flow module, capacities of nodes can
be given by node_column option. v.net.connectivity finds the
set of nodes of minimum total capacitiy separating the two given sets and
outputs map containing points on the positions of these nodes. Default
capacity, which is used when no column is specified, is one.
EXAMPLES
The following command finds the minimum number of intersections separating
roads on the left bank from roads on the right bank.
