I think a rule utilitarian might say that I should evaluate various algorithms for selecting a path and adopt the algorithm that will in general cause me to select paths with the highest overall net utility. Which, yes, is similar to the virtue ethicist (as described here) in that they are both concerned with selecting mechanisms for selecting paths, rather than with selecting paths… but different insofar as “virtuous” != “having high net utility”.
