I know this is similar to some earlier questions but I need a solution in QGIS.

I need to divide a large polygon coverage into n subset coverages in which polygons do not overlap. I know this is a "graph coloring problem" and I've seen solutions in ArcGIS and PostgreSQL but I'm looking for a way to do this in QGIS and I am not familiar enough with any of these systems to translate the code.

Welcome to GIS SE ! Can you add links to the similar questions on ArcGIS or PostgreSQL you found earlier ? – J. Monticolo Feb 03 '23 at 16:06
