AnyLogic provides traditional traffic lights which are triggered on the basis of time. I am creating a new road traffic management system in which I want to trigger traffic lights on the basis of the greatest car density among the four roads. Is there any function or element that would help me to do so?
No, you need to code it yourself.
That, however, is entirely possible. Just learn more about AnyLogic and how to write code, how to count cars on a road, how to manually switch traffic lights, etc.
Then, you can easily make it happen.

I'm working on my multiplayer game. The game is about pvp, you can shoot your friends and all stuff like that. I decided to make a score widget, which would show who is better. You might have seen something similar to what I'm talking about in fps games like csgo, valorant, overwatch, etc. Everyone should see the score.
I tried storing variables on servers character pawn. But pawn can be destroyed and score rollbacks to 0:0.
For replicated data that is persistent to respawn, you have two main options with the built-in game framework:
Create your own subclass of AGameState and the replicated data you want in it. There is one Game state and it is replicated on all clients. See what the official wiki (bottom of the page) says about GameState. You can store game-related data in it as total kill count in team deathmatches or team capture points in domination matches.
Create your own subclass of APlayerState and the replicated data you want in it. There is one Player state per player and it is replicated on all clients. See the official API of APlayerState. You can store each players' kill count in it for example or the number of objective a player captured. Make sure data is fed from the server and replicated to clients and not the other way around.
Unreal Engine comes with a powerful Game Framework, make sure to get familiar with it.
I'm new to LoRaWAN. I want to set up a new gateway in my country (Algeria North Africa) since it has no gateways yet. I'm having some difficulties concerning finding the appropriate frequency and some similar problems. On the lora alliance website, I found that the suitable frequency for my region is 915MHz but when you start a new setup in thethingnetwork gateway, there is no router or frequency for my region?
How to deal with that before buying a gateway?
And for those who are from Morocco, Tunisia, Egypt, and other countries, how did you pick the suitable frequency?
Here are some images for context:
First: I've never set up a gateway so I might miss some details.
It seems to me that you know almost everything already. What I can understand with my broken french is that you should indeed be using 915MHz as the frequency as the other, 868MHz, isn't allowed in Algeria for use.
It is really sad seeing TheThingsNetwork completely forgets a continent but my solution would be to register it as if you are in the US. Because the frequency (and I'm guessing also the power limit) is equal.
And about your question for the router selection: I would suggest picking ttn-router-eu. I don't know what internet cables connect to Algeria but I'm guessing that the closest is probably a link to Europe and thus the lowest latency router would be Europe. In the grand scheme of things it probably doesn't matter much though.
Maybe you could also raise these issues on the thingsnetwork forum as the frequency/region issue might just be that no one has put in the time/effort to add it to the options. For the router, it might even be possible to start running an application server/router for the ThingsNetwork so you can serve your region, but this is speculation on my part.

I'm looking at using cloud firestore to sync a multiplayer web game between players. However, this game involves continuous motion, like a player dragging a piece from one place to another. This would involve a stream of writes as its position changes. Given that the free plan is 20k free writes per day, and 20k writes can be done by a dozen players in a few minutes in this case, I worry that the cost would rapidly spiral out of control.
Is it impossible to do this sort of thing with firestore? I'm basically talking about a continuous websocket connection keeping the game data synced between players.
The limits of Firestore are well-documented. You haven't really said what hard limits you're concerned about exceeding. The only thing you've indicated is limits regarding the perpetual free tier, which can be easily exceeded by simply paying for the product based on your usage.
If you're not willing to pay for the service based on your needs, then you should probably look for another service. If you are willing to pay, then you need to do the math to figure out what your specific needs are, and if they can be met by the documented limits.
In the absence of more specific information about what you're trying to achieve, there's not much else that can be said.
I am trying to simulate a manufacturing system that uses Automated Guided Vehicles (AGVs) to carrying loads around the network to be processed. While the AGVs are travelling, it is ideal for them to pick the fastest route to the destination (not necessarily the shortest).
Here is my model
I am kind of stuck at trying to implement a route costing algorithm, because I am not too familiar with the intricacies of this program yet. Can anyone kindly give me some rough idea on how it can be implemented in pseudo code with the following scenario:
The load needs to move from A to B and there are three possible paths. However, there is congestion in the red highlighted areas that will cause the load to take a longer time to reach point B.
How can I read the network to check for congestion and also calculate the various times needed to go to point B?
I need to generate frames of animation to visualize a new graph layout algorithm. The frames will be generated on a server (50+ cores, 256GB RAM), but it is completely headless.
Every library that I have found wants to do the layout for me rather than allowing me to specify the position of each vertex manually. Perhaps I have overlooked something, but my Google-fu has failed me. My graphs are large; there will be millions of nodes and edges, and the graph structure will change over time, which is why I need to script the project.
I really don't want to waste a lot of time on the visualization, because that is not where the research is happening.
Does anyone know of a visualization tool that can work in a headless environment, that will allow me to specify the location of each vertex manually, and that can handle millions of nodes and edges quickly enough so that I can generate thousands of images?
