Neighbours & probabilities

[Degenderus]

Hello there,

I am trying to model the increase in probability to poach by individuals who have seen adjacent individuals poaching. This probability has a temporal nature, that is it only last one tick and then gets back to normal. 

To do that I have used the following code, but something went wrong. Could you help me figuring out?

;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

;; temporal poaching probability:

;; spiking after poached event from neighbouring poachers

;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

to setup-temporal-poaching-probability

 let temporal_poaching_probability poaching_probability

  if [ poached = TRUE ]

  [ ask fishers-neighbors [ count neighbors with [ poached = TRUE ] ]

 set temporal_poaching_probability poaching_probability * (count neighbors with [poached = TRUE] / 8)

 ]

tick                     

end

Hi,

It looks like the line "if [ poached = TRUE ]" is not correct.

poached is an agent property/attribute. So if you need to check this, you should check with respect to a specific agent or a group of agents.

for example, " if [poached] of turtle 0 = TRUE [..."

On the other hand if you are asking whether any poaching has happened in the previous tick, then you should define a new variable and set it to true based on whether one or more of the agents poached in the previous tick.

Hope this helps.

Best,

Pradeesh

Hi,

I am writing to ask if it is possible to get the sum of a link-value (which changes whenever two turtles get linked) at each tick when they got link? Thank you!

Best,
