Seeking Guidance on Controlling Coarsening Ratios in Networkit's nk.coarsening

[freshcoffee22]

Description: I've been exploring the functionalities of Networkit, particularly the nk.coarsening module for network coarsening. While I find the functionality quite powerful, I'm struggling a bit with understanding how to control the coarsening ratios effectively.

Details: I've reviewed the documentation but still find it unclear on the specifics of controlling coarsening ratios. Any insights, tips, or code snippets illustrating how one can adjust these ratios precisely would be immensely helpful.
