Linear Programming - Integral Linear Programs
... A linear program in real variables is said to be integral if it has at least one optimal solution which is integral ... Likewise, a polyhedron is said to be integral if for all bounded feasible objective functions c, the linear program has an optimum with integer coordinates. 1977, one can equivalently say that a polyhedron is integral if for every bounded feasible integral objective function c, the optimal value of the linear program is an integer ...

Famous quotes containing the words optimal and/or integral:

    In the most desirable conditions, the child learns to manage anxiety by being exposed to just the right amounts of it, not much more and not much less. This optimal amount of anxiety varies with the child’s age and temperament. It may also vary with cultural values.... There is no mathematical formula for calculating exact amounts of optimal anxiety. This is why child rearing is an art and not a science.
    Alicia F. Lieberman (20th century)

    Painting myself for others, I have painted my inward self with colors clearer than my original ones. I have no more made my book than my book has made me—a book consubstantial with its author, concerned with my own self, an integral part of my life; not concerned with some third-hand, extraneous purpose, like all other books.
    Michel de Montaigne (1533–1592)
