新手发问超简单问题,目前还处于研读范例码的阶段,边测边看结果来理解程序
9 C b* B+ L8 f/ N* e/ G& D. N: O其中有一段如下5 _7 q0 K6 Q% \3 F7 j: q: ]9 h
ask turtles with [ infected? = true ] ' h3 Y$ S0 ?8 A7 n# s8 S0 B! `
我原本以为这句会回传『所有』infected? = true 的 turtle( }/ L! o, o% U5 c" l
但看结果似乎不是这样。# ]8 z9 Z& v& w3 B
9 o8 r8 e# R7 [0 W% ^3 e
假设所有符合条件的有 5 笔% v; }- k; o" T7 Q; D, W
有时候回传 1 笔,有时回传 3 笔,是不固定的

agentset with [reporter]7 t3 M5 w; |7 I; d* Z9 |: m
Takes two inputs: on the left, an agentset (usually "turtles" or "patches"). On the right, a boolean reporter. Reports a new agentset containing only those agents that reported true -- in other words, the agents satisfying the given condition.
" y& k. [" r' L它只说回传 agents satisfying the given condition0 o: R& `. |' F B2 [5 t. {5 V
是否 with 回传的是『符合条件』的数据,而不是『所有符合条件』的数据 ?

想确定一下
