如何在 Netlogo 中保存多次迭代的输出数据

Question

我使用以下方法将模拟数据保存为 csv 文件：文件>导出>导出世界，适用于 1 次迭代。我想运行我的模型进行 1000 次模拟（甚至更多），并在每次迭代时保存数据。因为在每次运行时，输出都是不同的。我在 BehaviourSpace 中完成了一个示例，但我的输出数据并不像我使用 File>Export>Export World 得到的那样详细。我还尝试了 csv 示例，并且所有海龟自己的输出（感染？、感染 2？、感染 3？、易感？）都是相同的。

在 BehaviourSpace 中，在 Measure runs using these reports 选项下，我想统计海龟的数量——像被感染？，被感染1？但是当我这样做时，我得到了一个错误； 实验因语法错误而中止：您不能使用 INFECTED？在观察者的情况下，因为感染了？仅限海龟。

我的问题是如何将感染者、感染者 2 和感染者 3 的数量作为 csv 文件进行多次迭代，而无需手动进行（附件是我的代码）。非常感谢任何帮助。谢谢。

听起来您可以使用 BehaviorSpace 进行导出，只是代码格式不正确。 BehaviorSpace 比尝试创建自己的导出和管理它要容易得多。所以第一步是在你的界面上创建监视器来捕获你想要输出的度量，也许：

count turtles with [infected?]

一旦你让它们工作（并显示你想要的任何东西），那么你就知道你的语法是正确的，你只需将监视器的代码复制到 BehaviorSpace 实验的输出位中。
