81co-NP — Unsolved problems in computer science Is NP = co NP ? In computational complexity theory, co NP is a complexity class. A problem is a member of co NP if and only if its complement is in the complexi …
82Co-NP — In computational complexity theory, co NP is a complexity class. A problem mathcal{X} is a member of co NP if and only if its complement overline{mathcal{X is in complexity class NP. In simple terms, co NP is the class of problems for which… …
83NP-equivalent — In computational complexity theory, the complexity class NP equivalent is the set of function problems that are both NP easy and NP hard.[1] NP equivalent is the analogue of NP complete for function problems. For example, the problem FIND SUBSET… …
84Bounded variation — In mathematical analysis, a function of bounded variation refers to a real valued function whose total variation is bounded (finite): the graph of a function having this property is well behaved in a precise sense. For a continuous function of a… …
85Hilbert space — For the Hilbert space filling curve, see Hilbert curve. Hilbert spaces can be used to study the harmonics of vibrating strings. The mathematical concept of a Hilbert space, named after David Hilbert, generalizes the notion of Euclidean space. It… …
86Merkle-Hellman — (MH) was one of the earliest public key cryptosystems and was invented by Ralph Merkle and Martin Hellman in 1978. [Ralph Merkle and Martin Hellman, Hiding Information and Signatures in Trapdoor Knapsacks, IEEE Trans. Information Theory , 24(5),… …
87Structure (mathematical logic) — In universal algebra and in model theory, a structure consists of a set along with a collection of finitary operations and relations which are defined on it. Universal algebra studies structures that generalize the algebraic structures such as… …
88Merkle–Hellman knapsack cryptosystem — The Merkle–Hellman knapsack cryptosystem was one of the earliest public key cryptosystems invented by Ralph Merkle and Martin Hellman in 1978.[1] Although its ideas are elegant, and far simpler than RSA, it has been broken.[2] Contents 1… …
89probability theory — Math., Statistics. the theory of analyzing and making statements concerning the probability of the occurrence of uncertain events. Cf. probability (def. 4). [1830 40] * * * Branch of mathematics that deals with analysis of random events.… …
90Circuits over sets of natural numbers — Circuits over natural numbers is a mathematical model used in studying computational complexity theory. It is a special case of circuit, the object is a labeled directed acyclic graph the nodes of which evaluate to sets of natural numbers, the… …
