i tuoi sembrano problemi tipici di attraversamento di un grafo, tipo
DFS o BFS; non ho capito se ti interessa anche scoprire i Shortest
Paths o meno; credo che il plugin Network Analysis si occupi
principalmente di questi, cmq verifica perchè ne ho una conoscenza
abbastanza limitata;

tempo fa avevo messo a punto un plugin per QGIS 2.X che implementava
un pò di algoritmi tipici dei grafi fra cui anche quelli che cerchi;
purtroppo è un pò che non me ne occupo e quindi non sono fresco di
memoria; se ti interessa si può approfondire;

Re: [Qgis-user] Merge vector layers missing from menu in QGIS 3.0

[Alexandre Neto]

I wonder if we shouldn't encourage people to always look for it in
processing. With time, I think those entries could be removed.

Hi Richard, 

It's a bug in 3.0 fixed meanwhile (https://github.com/qgis/QGIS/pull/6472). 
Then should be available at next point release. 
Tell him to use the toolbox in the meantime.

[Qgis-user] Merge vector layers missing from menu in QGIS 3.0

[Richard Duivenvoorde]

Hi List,

On another mailing list, a Windows QGIS3 user asked why there is no
'Merge vector layers' in the *Vector* =>*Data Management Tools* menu.

In my current master build it IS there.
But in my Windows install it is indeed missing.

Was it layer added?

Will point to processing, but still wonderning.

Regards,

Richard Duivenvoorde

Re: [Qgis-user] QGIS3 Layout - North Arrow?

[delazj]

Hi, 

There's no north arrow specific tool in the layout; you need to use the image 
item. See 
https://docs.qgis.org/testing/en/docs/user_manual/print_composer/composer_items/composer_image.html

HTH,
