About the gnn

[StormstoutY]

Hi, I have a question about the communication radius. I notice that you adjust the radius dynamically to ensure the graph is connected. I wonder that if this setting will make each agents to communicate with at least one other agent? If I want to use gnn for communication as you did, do I need to make the graph connected? My project is about MAPF and I want the agents to communicate with other agents within a fixed communication radius. That means that some agents will not be in the communication graph so I'm not sure whether GNN works in this situation.
