nondeterministic turing machine
81GapP — is a counting complexity class, consisting of all of the functions f such that there exists a nondeterministic polynomial time Turing machine M where, for any input x , f(x) is equal to the number of accepting paths of M minus the number of… …
82Quantum mind — theories are based on the premise that quantum mechanics is necessary to fully understand the mind and brain, particularly concerning an explanation of consciousness. This approach is considered a minority opinion in science, although it does… …
83Nested stack automaton — In automata theory, a nested stack automaton is a finite automaton that can make use of a stack containing data which can be additional stacks.[1] A nested stack automaton may read its stack, in addition to pushing or popping it. A nested stack… …
84Deterministic context-free grammar — In formal grammar theory, the deterministic context free grammars (DCFGs) are a proper subset of the context free grammars. The deterministic context free grammars are those a deterministic pushdown automaton can recognize. A DCFG is the finite… …
85Mildly context-sensitive language — In formal grammar theory, mildly context sensitive languages are a class of formal languages which can be efficiently parsed, but still possess enough context sensitivity to allow the parsing of natural languages. The concept was first introduced …
86Controlled grammar — Controlled grammars[1] are a class of grammars that extend, usually, the context free grammars with additional controls on the derivations of a sentence in the language. A number of different kinds of controlled grammars exist, the four main… …
87Discontinuous-constituent phrase structure grammar — (DCPSG) (distinct from Discontinuous Phrase Structure Grammar/DPSG) is a formalism for describing discontinuous phrase structures in natural language, such as verb phrases in VSO languages. The formalism was introduced in the slightly more… …
88Minimalist grammar — Minimalist grammars are a class of formal grammars that aim to provide a more rigorous, usually proof theoretic, formalization of Chomskyan Minimalist program than is normally provided in the mainstream Minimalist literature. A variety of… …
89Esoteric programming language — An esoteric programming language (sometimes shortened to esolang) is a programming language designed as a test of the boundaries of computer programming language design, as a proof of concept, or as a joke. There is usually no intention of the… …
90COMPUTER SCIENCE — The term Computer Science encompasses three different types of research areas: computability, efficiency, and methodology. General Introduction Computability deals with the question of what is mechanically computable. The most natural way to… …
