WebWhen you push an element into an empty or full vector, we need to: allocate a new block of memory that is larger. move all the elements we have already stored in the previous block into the new one. Both these operations are expensive and we want to avoid them as much as possible, if you can, sometimes you just accept things the way they are. great stone of blakely

Vector optimization is a subarea of mathematical optimization where optimization problems with a vector-valued objective functions are optimized with respect to a given partial ordering and subject to certain constraints. A multi-objective optimization problem is a special case of a vector optimization problem: The objective space is the finite dimensional Euclidean space partially ordered by the component-wise "less than or equal to" ordering.
