What's reduction and its relationship with levels?

[NIRVANALAN]

Hi, I read your scipts and seems that we need to control the coarsen level by reduction_ratio in bash. what;s their relationship and how can I determine coarsen level based on that variable?

when I try reduction_ratio=3 or 4 on cora, the final coarsen level is the same(level=2) and the size of coarsed graph remains the same, so I am cuious.

Hi, we cannot directly set the coarsen level, but you can try a large reduction ratio first and then to see the relationship between reduction ratio and coarsen level via the printing information.
