What is the use of `c` and how can its value be computed?

The point of such a factor in general is that you want to be able to calibrate the scores you get, by forcing them to be within a specific range like $[0,1]$. In particular, this factor would be computed (in principle) by getting the rank of all pages and then dividing by their sum.
