That is actually acceptable and expected. I just want the information
between the one-hop neighbors to be relatively timely. The only requirement
for the further away robots that I have is that if the robot positions and
the world are static, then the topology information should more or less
stabilize over time. Random fluctuations are OK; they can be averaged away
without any trouble. Does that make sense?
