Cuboids pruning

Hi,

I saw mentions of cuboids pruning.  I like the sound of that! :)
Can anyone point me to anything that explains how/why/when cuboids can be
pruned?

Or maybe the answer is simply: when cuboids are combined in the full cube
they are no longer needed, so they can be removed?

Thanks,
Otis

Page 7, 8, 9, 10, 14 of below slides explains how partial cube is defined
in Kylin.
