我有两个品种:步行者(动态(和事件(静态(。步行者沿着链接(街道(移动并随机转弯。事件随机放置在一些未知节点上。
每个智能体如何知道他在到达一个事件之前所遵循的路径?我想知道是否可以将其保存在列表甚至矩阵中,其中每一行都是查找不同事件的路径,但我不知道如何收集这些节点/链接。
如果步行者发现一个事件,他如何记录它以及如何保存该数据?
非常感谢您的帮助
下面是对模型库中"链接行走的海龟"代码示例的修改,其中步行者现在有一个路径变量。当步行者移动到下一个节点时,它会使用 lput
将新节点放在列表的末尾。一旦此列表到达模型中的"事件",将由您来管理或清除此列表。您可能还希望修改此方法以存储多个路径而不是单个路径。
