nw:weighted-path-to

nw:weighted-path-to target-turtle weight-variable

Like nw:path-to, but takes link weight into account.

Example:

links-own [ weight ]
to go
  clear-all
  create-turtles 5
  ask turtle 0 [ create-link-with turtle 1 [ set weight 2.0 ] ]
  ask turtle 1 [ create-link-with turtle 2 [ set weight 2.0 ] ]
  ask turtle 0 [ create-link-with turtle 3 [ set weight 0.5 ] ]
  ask turtle 3 [ create-link-with turtle 4 [ set weight 0.5 ] ]
  ask turtle 4 [ create-link-with turtle 2 [ set weight 0.5 ] ]
  ask turtle 0 [ show nw:weighted-path-to turtle 2 weight ]
end

Will output:

(turtle 0): [(link 0 3) (link 3 4) (link 2 4)]
