向海龟询问链接另一端的最小变量

Question

我目前正在解决一个问题，我有两个代理集：买家和卖家，卖家与买家相关联。我的问题是：如何要求买家选择卖家变量（价格）的最小值。

我认为我可以通过像这样的原语来做到这一点：

ask buyers with [count my-in-links > 1][
    min-one-of price of other-end ;; something like this, this don't work obviously just wanted to show you my idea.
]

或：

ask buyers with [count my-in-links > 1][
     if min-one-of in-link-neighbors of in-link-neighbors price  < 1[
       set color yellow
     ]
  ]

谢谢。

Answer 1

我猜你需要这样的东西：

... min-one-of in-link-neighbors [price]

例如，如果您想将最便宜的卖家作为代理商存储在变量中：

ask buyers with [count my-in-links > 1][
  let cheapest-seller min-one-of in-link-neighbors [price]
]

或者您可以直接访问该卖家的价格，例如将其存储在变量中：

ask buyers with [count my-in-links > 1][
  let cheapest-price [price] of min-one-of in-link-neighbors [price]
]
