You are correct on both counts, it is missing in the documentation - I'll fix that, and it is modularity being measured.
Efficiency favours granular/fine-grained clusterings, modularity favours coarser clusterings. At some point I looked at e.g. adding the two up to see if that would give a nice parabolic maximum, but to no avail. Any single criterion (e.g. efficiency/modularity/conductance) will favour a certain granularity range. For more complex graphs that admit cluster structure at different levels I don't think any of them can be favoured, unless of course they happen to pick the granularity range that best suits your application.
Got it, thank you for the quick reply and explanation! Closing this "issue".
Greetings,
Not an issue, but a question about the output from clm info: I understand that 'eff' is efficiency, 'mf' is mass fraction, and 'af' is area fraction, but I'm not sure what 'mod' is short for. Based on the values, I infer that this might be 'modularity', but is this correct? I couldn't find a description of 'mod' in the clm info documentation online. Apologies if I missed it somewhere. Below is an example of the output:
eff=0.69641 mod=0.99225 mf=0.99317 af=0.00044 src=out.seq.mci.I12 ncl=33952 max=2016 ctr=162.3 avg=10.9 min=1 DGI=2016 TWI=1067 TWL=99 sgl=19635 qrt=26608
I'm using mcl version 22-282.
