WebA set is the mathematical model for a collection of different [1] things; [2] [3] [4] a set contains elements or members, which can be mathematical objects of any kind: numbers, … WebA partially ordered set is a directed-complete partial order ( dcpo) if each of its directed subsets has a supremum. A subset of a partial order is directed if it is non-empty and every pair of elements has an upper bound in the subset. In the literature, dcpos sometimes also appear under the label up-complete poset.
