I flagged it as a duplicate. I don't recall seeing the subtle difference, and in any case it's **your** responsibility as the asker of both questions to put them in context with respect to each other: both of them link to an external site but don't mention the other question on this site.

I still believe that both questions should be closed until you edit them to make it actually possible to answer them, by explaining how to quantify the attribute which you want to maximise.
