QUESTION
I have a question regarding NetLogo. I want to create N blue patches, surrounded by grey patches (and some turtles, but not important for this question). These patches should NOT overlap, and have at least 1 black patch between them. However, they DO overlap.
What did I do wrong? And how should I fix it?
Thanks in advance!
...ANSWER
Answered 2022-Mar-31 at 13:07the problem with your code is that Netlogo first chooses N random patches for which the condition applies, puts them into an agentset and then lets them execute the command in turn. It doesn't reevaluate in between if all conditions still apply to all patches that were initially chosen.
Instead, I suggest repeat and one-of so that each new patch is chosen after the previous one has finished.

I was trying to capture a piece of the subtitle from a youtube video. I scraped the data but now I'm facing difficulty in formatting it. I want to delete the timestamps and extra newlines(\n) and get it in a nice string format. I want to know the best way to tackle these problems so that in the future I could fetch the properly

I have two DataFrames of 20 rows and 4 columns. The names and value types of the columns are the same.
One of the columns is the title, the other 3 are values.
ANSWER
Answered 2022-Mar-12 at 18:19Since you want 3 separate DataFrames, we could use a loop (if you want a single DataFrame, we could do a similar job a bit differently).
We could unstack df2 and iteratively subtract it from the repeated columns of df1:
QUESTION
So basically I am building an evacuation model for my university lecture hall. The problem I am facing is that the people always walk over the gray patch that is not supposed to be walked over even though I have included the procedure to avoid walls in the code. This is the current code for my evacuation model. Also is it possible for the turtles to stop moving when arrived at the exit which in this case is the green patch? Also please bear in mind that I only just started learning Netlogo so If any improvements in the coding itself is much appreciated.
...ANSWER
Answered 2022-Mar-01 at 20:51You run "move" in which the turtles face a direction, then move. Then you run "avoid" in which the turtles look for gray and turn.
So your turtles have already moved before they look for gray.
My advice: aim, then correct, then move. Note that this very simple navigation rule will not move like a person would move.
QUESTION
I'm trying to solve a problem of speed in creating turtles in the NetLogo world.
I have a model that has a world with a size of 600X600. I, too, have 31 turtle profiles (each turtle can only born in a specific habitatcover type or habitatcover set (see ValidHabs variable in the code). In the code, too, there are 2 variables that are metabolism with 2 levels (list1 in the code) and reproduction with 2 levels (list2 in the code). Also, I would like to have at least 200 turtles born in the world or more in this world.
The problem is that it is taking a long time for turtles to be born in the world. Have I already created a switch called Display? to speed up the creation of the turtles. I also set it to faster speed and it still takes a long time to create the turtles.
Does anyone know how I can speed up the creation of turtles based on my code?
I don't know what else to do to speed up the code... I appreciate any kind of help :)
Thanks in advance

Answered 2022-Feb-17 at 20:33I'm afraid I did not look for the particular problems in your code, but there is general advice on speeding up models here: http://jasss.soc.surrey.ac.uk/20/1/3.html with updates here: http://www.railsback-grimm-abm-book.com/jasss-models/
I'm pretty sure that some of the advice applies to your code.
QUESTION
We are trying to solve the following problem:
Each agent has its specific code and at each iteration the list of agents alive in that iteration is updated. We want to calculate how many agents are die of each code present in the list per iteration. We have these procedures below (code). Obs: We need to use the profile list because of the outputs that are exported by turtle profile
Sorry for the big code below, but we tried our best to reduce it to be reproducible code
Thanks in advance
...ANSWER
Answered 2022-Feb-16 at 19:15Deaths as you have it is a global variable, which means that any time any turtle accesses it (either to update or read), they are all "sharing" the same value. Instead, you need to track deaths for each profile type. The way you have it, where profiles-code differentiates the different turtle types, you can tackle this a few ways- for example: you could create specific Death trackers for each profile type (eg. Death-M1R1, Death-M1R2... etc.) and output that as needed; or you could use a list, where you update the items in the list that correspond to a specific profile; or you could use a list of lists and use position to grab the death value for a different breed; or you could use the tables extension, which is the example I will show below because I think it's the cleanest and most explicit.
The tables extension allows what is similar to a dictionary structure if you've used that in other coding languages, where you have a {KEY: VALUE} pair such that if you enter the KEY you get out the VALUE. So the general workflow here is to build a dictionary to store the name and death count for each profile type. Then, anytime a turtle dies it will update the death count for its profile type in the dictionary.
To keep it simple, I've made only minor changes to your code above, and added comments where I made (most) updates:
QUESTION
I'm not able to assign the first item value of a list to a turtle variable. For example? I have list3 that has 1 item, that is: list3: [[5 2]]
I would like the first value of list 3 item 0 to be assigned to reproduction (ie 5) and the second value of list 3 item 0 to be assigned to metabolism (ie 2).
How can I do this?
Thanks in advance
...ANSWER
Answered 2022-Feb-16 at 01:01You can easily understand how to do this by playing in the Command Center and seeing how NetLogo responds to your calls to the list.
Just create a global variable in the Code tab, as globals [my-list], and then follow my statements in the Command Center:
QUESTION
I'm trying to implement an output which is an export from the View. I got help from this link: How to export the world of NetLogo 6.2 coloring only the patches that were born turtles? I greatly appreciate Luke C's help, as I managed to implement part of what I want.
However, I still haven't managed to generate the images by turtle profile. I have 16 turtle profiles (see ValidHabs).
I would like for example to export an image for each of the 16 turtle profiles.
For example, turtle profile 1 (can only born and hatch in habitatcover 1), so:
...ANSWER
Answered 2022-Feb-09 at 04:11When you are supplying code, it is recommended that you start from scratch rather than trying to pare down your existing model (see How to Ask and How to create a Minimal, Reproducible Example). This will help in (at least) two major ways:
- It makes your code more readable and therefore makes you more likely to get a useful answer, since other users on this site will have an easier time understanding the problem if they don't have to also try and understand what part of the code is unrelated to the actual problem.
- It makes it more likely that you will solve the issue yourself, or at the very least will help you better understand where the problem is coming from.
I'd recommend having a really solid crack at trying to follow the guidelines above whenever you post a question. As it stands, the code you supplied is way more than what's actually needed for the question itself, which for me would boil down to: "How do I change the file name for multiple experiments / simulations?" This question has been answered before in different ways that may suit your needs- if the code example below does not clear things up, have a look through those other questions and keep in mind the "Search and Research" component of the How To Ask help page.
For a standalone example, that is really just a refinement of Charles' answer in the first link above:
QUESTION
I don't really know how to export the following output...
I have 16 turtles profiles, which refers to the non-repeating combination of habitatcover types (see ValidHabs variable)
In the model, it starts with 10 turtles that can reproduce or die.
I would like to generate an output in which the whole world turns white and paints magenta only where turtles were born, that is, the 10 turtles that started the world and then the new turtles that emerged through the reproduction process. And that this came out by turtle profile. I have looked up the NetLogo dictionary and I believe I should use the export-view command
But, I still couldn't execute in a simple code that can only export in image form the patches that only existed turtle (painted in magenta) at the end of all ticks (that is, all patches that had turtles taking into account all ticks ) for that turtle profile.
What I've managed to do so far is below.
Any kind of help will be very welcome :)
Thanks in advance!
...ANSWER
Answered 2022-Feb-08 at 03:53I think the best way to track this is a patches-own variable to track if a turtle was ever born on the patch. In this example code I've called that turtle-born-here, set the variable to false in the setup, then update the variable any time a turtle is 'born' (either on setup, or during go).
QUESTION
I have a doubt/intrigued by a NetLogo situation. Also, I don't know if there is a solution and the exact reason for this to occur.
I made a small code to exemplify my question...
What happens is the following:
- When I click on the setup button and then on the go and let for example 20 ticks pass, I have the following movement of the turtles (see figure below)
- But, if you press the setup button, then a button created in the interface to show and disapear the turtles labels (turtle labels) and then press go and leave the 20 ticks, another movement of the turtles appears (see figure below)
I would like to know why this happens? Will it be by the use of one-of?
And if there is any solution, because I need to see the turtle label in the interface to follow the model and check its operation.
If anyone has any ideas on how to resolve this and why this happens, I would appreciate it.
Thanks in advance :)
...ANSWER
Answered 2022-Feb-04 at 01:47Great job with the minimum reproducible example, that's really helpful! If I understand what you're asking, you're wondering why, despite setting random-seed, there is a difference between your two runs? If that's the case, I think it's because you are doing an extra action (ask turtles [...) that relies on randomness to operate. When you ask turtles, the turtles act in a random order. So, if you need the turtles to move the same way each time, one quick way around that is to set the random number right before the action you're trying to replicate. For example, if I change your move-turtles to:
