nw:mean-path-length

nw:mean-path-length

Reports the average shortest-path length between all distinct pairs of nodes in the current context.

Reports false unless paths exist between all pairs.

Example:

links-own [ weight ]
to go
  clear-all
  create-turtles 3
  ask turtle 0 [ create-link-with turtle 1 [ set weight 2.0 ] ]
  ask turtle 1 [ create-link-with turtle 2 [ set weight 2.0 ] ]
  show nw:mean-path-length
  create-turtles 1 ; create a new, disconnected turtle
  show nw:mean-path-length
end
