我有一个大约有4000个节点的网络，其中大约50个节点只有一个链接。当我运行nw：weighted-path和nw：weighted-distance时它们都能很好地工作，但是当我尝试使用nw时：mean-weighted-path-distance netlogo挂起（没有响应），最终导致堆失败。我尝试使用连接图示例重现它，一切运行良好。我已经使用与5.1.0和5.2.0捆绑在一起的网络扩展来实现这一点 我想知道是否有其他人遇到过这个以及他们是否能够解决这个问题？
编辑1（已添加代码）
我有称为公路和品种的链接，称为道路和起源，均由高速公路连接
let road-set (turtle-set roads origins)
nw:set-context road-set highways
output-show nw:mean-weighted-path-length "my-highway-length"
编辑2 [使用Netlogo 5.2]我收到GC过载错误，如下所示
