  set group "A" ifelse-value (color = red) [ ] [set group "B"]
]

; 识别特定属性的乌龟
ask turtles with [group = "A"] [
  ; 执行操作

create-turtles 100
ask turtles [
  ifelse-value (random-float 1 < 0.5) [
    set group "Group1"
  ] [
    set group "Group2"
  ]
]

; 识别特定群体的乌龟
ask turtles with [group = "Group1"] [
  ; 执行操作

; 识别在特定区域的乌龟
ask turtles [
  ifelse-value (xcor > 0 and xcor < 10 and ycor > 0 and ycor < 10) [
    set group "Area1"
  ] [
    set group "Other"
  ]
]

; 识别特定区域的乌龟
ask turtles with [group = "Area1"] [

    set group "Group1"
  ] [
    set group "Group2"

ask turtles [
  ifelse-value (xcor > 0 and xcor < 10 and ycor > 0 and ycor < 10) [
