使用中介中心性的随机游走问题

Question

我创建了一个由10个节点组成的小型网络，并相互链​​接。然后我使用网络扩展计算每个节点的中介中心性。 现在，我想实现随机游走算法。 首先，当我创建walker时，我想将它们放在具有最大值介于中间的一个节点上。 然后我想将walker移动到具有最大值betweennes的link-neighbor的新位置。 但是，我不知道如何实现这个逻辑，请指导和帮助我。 这是我的代码：

        extensions [ nw ]
        breed [ nodes node ]
        breed [ walkers walker ]
        walkers-own [ location ]
        to setup
        clear-all
        make-nodes
        end
        to go
        random-walk
        end
        to make-nodes
         create-nodes 10 [
         set shape "circle"
         set color white
         setxy (random-xcor * 0.95) ( random-ycor * 0.95)
         ]
         ask nodes [
         create-link-with one-of other nodes ]             
         end

         to make-walkers
          create-walkers 3 [
          set color green
         **set location one-of nodes**
          move-to location
          ]
          reset-ticks
           end
          to random-walk
           ask links [ set thickness 0 ]
           ask walkers [
          **let new-location one-of  [link-neighbors] of location**

          move-to new-location
           set location new-location
            ask location [
            set color red] 
            tick
           end

         to betweenness
         centrality [ [] -> nw:betweenness-centrality ]
         end
