问题描述
我已经编写了Netlogo代码，以使海龟轮流更改值。乌龟是沿着水流放置的农民。他们将根据谁的人数在空间用水量上有所差异，并且将根据谁的人数在轮到他们时取水。代码运行良好。每个滴答声都比平时花费更多时间。我看到完整的模型将花费更多时间来运行。是否可以更改这些代码以使模型按照所附图片中给出的设置模式有效运行？ 感谢您的帮助

解决方法
您对这些模型中的时间工作原理有根本的误解。命令tick指示模型提前时钟。那是嵌入在go过程中的，并且go过程（大概）运行每个刻度。前进过程中需要的是在一个时间步中发生的事情。相反，此刻，您要追加另外五年的时间表。
如果您需要一个时间表，因为您希望每个乌龟都转一圈，然后在下一个滴答声中移到下一只乌龟，请在设置过程中而不是在执行过程中构建时间表。您可能还应该使用mod运算符，因为它是一个周期，因此您不需要五年的计划，只需存储一个周期即可。您也不需要使用lput来单独添加每个项目，只需一次提供整个列表即可。
类似这样的事情（请注意，我已经完全放弃了时间表，只使用mod进行循环）：
breed [farmers farmer]
farmers-own [water irrigation-turn]
to setup
clear-all
create-farmers 30
[ set label who
set size 2
]
ask farmer 0 [ setxy min-pxcor + 1 0 set irrigation-turn 0]
ask farmer 1 [ setxy min-pxcor + 1 2 set irrigation-turn 1]
ask farmer 20 [ setxy min-pxcor + 1 4 set irrigation-turn 2]
; and similarly for remaining farmers
reset-ticks
end
to go
irrigate
tick
end
to irrigate
ask turtles with [irrigation-turn = (ticks mod count farmers)]
; do whatever it is they do when it's their turn
ask turtles with [irrigation-turn != (ticks mod count farmers)]
; do whatever it is they do when it's not their turn
end
或者，如果您想保留一个时间表（例如，由于有些星期不适合一个周期），请直接构造一个。例如，如果您想要4周周期的第3周，则只需执行以下操作：
set irrigation-turn [ 0 0 1 0]
还有其他一些使用reduce sentence n-values的技术来做更长的列表，但是我认为如果没有它们，您的效率问题就可以解决。
您的速度问题是因为您使用的是一个长长的列表：
set irrigation-turn lput 1 irrigation-turn
您需要确保列表相对于刻度线不是线性增长的
