我正在编写一些代码,为流感正在流行的人群接种疫苗。该代码有两种名为HOV和HEV的疫苗。 HOV给我想要靶向的人群比例提供相同的疫苗株。 HEV给予该比例不同的疫苗株(随机测定)。
我想要一行代码,在每次模拟的第一个刻度中报告每只海龟的免疫状态。免疫状态在该模型中由整数表示,因此不同的龟将具有不同的免疫标签,这取决于它们是否接种疫苗。我希望在最终的BehaviourSpace .csv输出中,每次运行的第一个滴答中包含所有海龟的免疫标签数组的列。
我的代码如下:
extensions [csv]

任何建议都将不胜感激!谢谢!
答案 0 :(得分:1)
第二个想法 - 我想我找到了答案!我基本上创建了一个列表,列出了一旦setup命令完成就存储免疫标签。我的更新代码如下:
extensions [csv]
globals [initial-immunity-array epidemic-threshold cumulative-infections proportion-of-infection currently-infected peak-prevalence vax-strain]
turtles-own [infection-period infection-number tflu-strain immune-label ant-distance cross-immunity]
patches-own [fomite-age pflu-strain]
to setup
clear-all
setup-turtles
set initial-immunity-array (list t-sorted-immunity-list)
print initial-immunity-array
reset-ticks
end
to setup-turtles
create-turtles 100
ask turtles [setxy random-xcor random-ycor]
ask turtles [set color white set infection-number 0 set immune-label -999999999999 set tflu-strain -999999999999 set vax-strain -999999999999]
ask one-of turtles [set color red set infection-period 0 set infection-number 1 set immune-label 0 set tflu-strain 0]
if vaccine = "HEV" [
ask n-of prop-vax turtles with [color = white] [set color blue]
ask turtles with [color = blue] [
ifelse (one-of [1 2] = 1) [
set vax-strain (random ((2 * drift-size) + 1))]
[set vax-strain (-1 * random ((2 * drift-size) + 1))]
set immune-label vax-strain
]
]
if vaccine = "HOV" [
ask n-of prop-vax turtles with [color = white] [set color blue]
ifelse (one-of [1 2] = 1) [
set vax-strain (random ((2 * drift-size) + 1))]
[set vax-strain (-1 * random ((2 * drift-size) + 1))]
ask turtles with [color = blue] [set immune-label vax-strain
]
]
set epidemic-threshold "no"
set cumulative-infections 0
set peak-prevalence 0
end
to-report t-sorted-immunity-list
report map [i -> [immune-label] of i] sort turtles
end
to go
if ticks = flu-season-length [stop]
move-infecteds
move-uninfecteds
transmit
mutate
update-immunity

track-epidemic
set cumulative-infections (count turtles with [infection-period = 1] + cumulative-infections)
set proportion-of-infection (100 - (count turtles with [immune-label = -999999999999]))
set currently-infected (count turtles with [infection-period = 1])
end
