I'm reading a paper about Multi-Objective Optimization Problem. I understand Optimal in Pareto sense, and I even know what is Pareto-Optimal Front somehow. But I can't find a relationship between the word Front and the concept. So, what's the meaning of this word in this context?

I think it is sort of short for "frontier" (as in boundary between one thing and another.) The two canonical examples would be a weather front (the boundary between a cold airmass and a warm airmass) and a military front (the boundary between the areas controlled by a pair of belligerent armies).

$\begingroup$ Very interesting. Thank you very much. Indeed, visually, the set of objective vectors corresponding to Pareto optimals, is a boundary for all possible objective vectors. $\endgroup$ – mrmowji May 16 '14 at 17:39
