I used to think I understand Linear Programming, and the transportation problem. Is there a relationship between this and the Markov formulation? I'm totally confused now. Posts like this make me feel guilty about not reviewing them once in a while. And I guess while I'm at it with the questions:

>We have to add an artificial source and sink on both sides of our bipartite graph to ensure flow conservation

Wasn't there a hack with the slack/surplus variable in the LP constraints to deal with this or was it a dummy variable? Pretty sure that was able to handle the case where supply was not equal to the demand.

Also, how were cases where the user stopped using GitHub altogether or a new user started programming are handled?
