What you set is in fact bgb=6000,6000 which sets the size of the module. There were indeed plans to add a tag called bgp directly into OMNeT++ which would introduce an offset, but at the end it was not implemented. The reason is that once you go down into that rabbit hole, you want to implement also scaling and then rotation etc. So the default display string based visualization left as simple as possible and all these transformation stuff was left for the model code.

So indeed, SceneCanvasVisualizer in INET has a viewScale and viewTranslation parameter that can be used for these purposes.

Use more_itertools.powerset which will result in list of tuples so convert it into list of list using map()

The Unet simulator supports multiple levels of motion models depending on the required complexity in the simulation.

The NodeInfo agent in each simulated node implements a basic dynamics model. The model is turned on using the mobility flag which can be set in a simulation script or directly on the NodeInfo agent. When mobility is enabled, the agent automatically updates location based on motion parameters such as speed and heading using the simple dynamics model. This can be handy to simulate the motion of a node, for example, an AUV swimming away from an underwater modem.

We can easily do this by manually updating the parameters of one of the nodes in a simulation. Use the 2-node-network example from Unet IDE. The "Map" view of the IDE is handy to visualize the motion of nodes. Connect to the WebShell of Node A and set the mobility, heading, and speed parameters. As the simulation continues the location of Node A will continue to be updated based on the speed and heading.

This line indicates it's training on one batch, not one sample:

$unwind

Deconstructs an array field from the input documents to output a document for each element. Each output document is the input document with the value of the array field replaced by the element.

$addToSet

Returns an array of all unique values that results from applying an expression to each document in a group of documents that share the same group by key. The order of the elements in the output array is unspecified.

$group

Groups input documents by the specified _id expression and for each distinct grouping outputs a document. The _id field of each output document contains the unique group by value. The output documents can also contain computed fields that hold the values of some accumulator expression.

Your kernel command line says "console=tty0", which means "please send console to the first virtual terminal", ie to the graphics device. But there is no graphics device in the machine you're running (you say "-nographic" on your QEMU command line and the kernel says "Console: colour dummy device 80x25"). So what happens is that you see the initial bootup messages via the "uart8250" earlycon (ie the serial port), but as soon as the kernel gets to a point where it can honour your command line request, it enables tty0 (which goes nowhere) and disables uart8250 (so you see no further output).

You need to tell the kernel to send the console output to the serial port if that's where you'd like to see it appear, which for the malta board I think you can do by using "console=ttyS0" instead. Alternatively, you can drop '-nographic', make sure your kernel has the driver for the VGA card built in, and leave "console=tty0" and you'll see the console on the virtual console on the graphical window.

If you look at the README for the website you downloaded your image files from you'll see that it does indeed suggest using "console=ttyS0".

I ran your simulation using the code you provided and managed to reproduce the error. Tracing through the logs, I found that the error occurred on the third motion update for node B, whereas your simulation script only seemed to have 2 legs in the motion model. That gave me a hint as to what the problem was.

Your motion model states:

It's pretty easy to add what you're after. You just need to map alpha to dclass and then set the values you want using scale_alpha_manual().
