Yes, I read that page and it was that paragraph that made me want to learn more.
For example, that pages says: “-pc_gamg_threshold 0.0 is the most robust option (the reason for this is not obvious) ...” Where can I find more math-based background on this subject? I mean, some text that describes the methods and not just the implementation as the source code at gamg/util.c so I can better understand what is going on.
