<p>Haha, macro “happiness” maximization made me laugh. I can just imagine a computer monitor sitting there, frowning and tilting its head as it moves people around to make itself happy. Anyway, the logarithm apparently gives as many people their first choice as possible in terms of maximization policy - I know I read that somewhere. I have no clue how really unlucky people ended up getting their fourth and fifth choices though :/</p>
