sum of sets
31Maximum coverage problem — The maximum coverage problem is a classical question in computer science and computational complexity theory. It is a problem that is widely taught in approximation algorithms. As input you are given several sets and a number k. The sets may have …
32Probability space — This article is about mathematical term. For the novel, see Probability Space (novel). In probability theory, a probability space or a probability triple is a mathematical construct that models a real world process (or experiment ) consisting of… …
33Ordinal arithmetic — In the mathematical field of set theory, ordinal arithmetic describes the three usual operations on ordinal numbers: addition, multiplication, and exponentiation. Each can be defined in essentially two different ways: either by constructing an… …
34Direct product — In mathematics, one can often define a direct product of objects already known, giving a new one. This is generally the Cartesian product of the underlying sets, together with a suitably defined structure on the product set. More abstractly, one… …
35Dempster–Shafer theory — Prof Arthur P. Dempster at the workshop on Belief Function Theory (Brest 1 april 2010). The Dempster–Shafer theory (DST) is a mathematical theory of evidence.[1] It allows …
36Convex hull — The convex hull of the red set is the blue convex set. See also: Convex set and Convex combination In mathematics, the convex hull or convex envelope for a set of points X in a real vector space V is the min …
37Adjoint functors — Adjunction redirects here. For the construction in field theory, see Adjunction (field theory). For the construction in topology, see Adjunction space. In mathematics, adjoint functors are pairs of functors which stand in a particular… …
38Complement (music) — Traditional interval complementation: P4 + P5 = P8 In music the term complement refers to two distinct concepts. In traditional music theory a complement is the interval which, when added to the original interval, spans an octave in total. For… …
39Space (mathematics) — This article is about mathematical structures called spaces. For space as a geometric concept, see Euclidean space. For all other uses, see space (disambiguation). A hierarchy of mathematical spaces: The inner product induces a norm. The norm… …
40Game theory — is a branch of applied mathematics that is used in the social sciences (most notably economics), biology, engineering, political science, computer science (mainly for artificial intelligence), and philosophy. Game theory attempts to… …
