未将结果正确写入文件的Net徽标

Question

我在Netlogo中运行模拟，通过编码自动将结果发送到电子表格。这发生在模拟结束时，以保存每个人的变量(例如，身份、归属范围大小等)。电子表格的结果通常看起来很好，但是当使用BehaviorSpace时，有时来自个人变量的数据没有被正确地打印出来(例如，错误列中的数据或丢失的数据，请参见下面的屏幕快照)。

我想知道，在BehaviorSpace并行运行期间，当模拟同时结束时，这会导致同步写入文件。这有可能发生了吗？除了这些值得注意的问题外，我是否应该合理地相信，剩下的结果被正确地打印到了桌面上？最重要的是，如何避免这些错误打印到文件中？示例代码如下。

额外的问题解决了:我认为打印日期和时间会识别独特的模拟运行，但事实并非如此，因为每个海龟的变量需要超过一分钟才能打印到文件中。是否有一种为每次模拟运行添加唯一标识符的快速方法？

谢谢!

to start-output-file ;; Observer procedure, called from setup. 
  set-current-directory "C:\\... 
  file-open "Table_results.csv"
  ;; Define the names of the variables:
     file-type "Run,"
     file-type "Landscape,"
     file-type "Individual,"
     file-type "Home range size,"
     ;; ... and so on, ~60 results saved for each individual            
     file-print ""
     file-close ]
end

to end-simulation ;; Observer procedure, called from go.
  write-outputs
  file-close 
end

to write-outputs ;; Observer procedure, called from end-simulation.
  set-current-directory "C:\\...
  file-open "Table_results.csv"
  ask turtles
    [ file-type (word date-and-time ", ") ;;<---Would like a unique run identifier here instead if possible.
      file-type (word Landscape ", ")
      file-type (word Who ", ")
      file-type (word Home-range-size ", ")
      ;; ...
      file-print "" ]]    
end

Update/Solution:我的解决方案是让每个模型运行，写到一个单独的CSV。这允许我保存每个代理变量的结果。每个文件都有一个唯一的标识符，所以以后不会被覆盖或添加到其中。然后，所有的CSV都可以使用程序R轻松地导入和组合。

示例代码：在安装过程中定义CSV文件名，并要求海龟将其结果写入文件：

extensions [ csv ]
globals [ filename ] ;; Will define as the date/time and BehaviorSpace run #.

to setup
  clear-all 
  let run-ID (remove-item 6 (remove-item 7 (remove-item 8 (remove "-"(remove " "(remove "." (remove ":" date-and-time)))))))
  set filename (word "Results, " run-ID ", " word behaviorspace-run-number".csv")
  file-open filename
  start-output-file
  ;; Etc.
end

to start-output-file ;; Called from setup.
   file-open filename
   file-type "Turtle identity,"
   file-type "Home range size,"
   ;; Etc., rest of column headers.
   file-print ""
end

to end-simulation ;; Observer procedure, called from go.
  ask turtles [ write-outputs ]
  file-close 
end

to write-outputs ;; Called from end-simulation.
  file-type (word Who ", ") 
  file-type (word home-range-size ", ") ;; (Turtle variable for home range size.)
  ;; Etc., i.e., each turtle variable you are writing to file.
  file-print ""
end

希望这能帮助其他人做一些类似的事情，或者注意到他们从BehaviorSpace输出的CSV中类似的奇怪之处。
