平均路径:
Pajek2.05版本(http://mrvar.fdv.uni-lj.si/pajek/)里有:
Net>Parths Between 2 Vertices>Distribution of Distances>From All Vertices
执行之后,可以在报表界面看到类似于下面的结果:
Distribution of Distances
------------------------------------------------------------------------------
Working...
Number of unreachable pairs: 2124
Average distance among reachable pairs: 3.22881 (这是平均最短路径)
The most distant vertices: f49 (22) and f41 (14). Distance is 8. (这是直径)
