Query: Local Interactions for Cohesive Flexible Swarms   Distributed gathering algorithms aim to achieve complete visibility graphs
via a "never lose a neighbour" policy. We suggest a method to maintain
connected graph topologies, while reducing the number of effective edges in the
graph to order n. This allows to achieve different goals and swarming
behaviours: the system remains connected but flexible, hence can maneuver in
environments that are replete with obstacles and narrow passages, etc.
