- noun Technical meaning of acceptor (mathematics, algorithm, theory) (FSM or "Finite State Automaton", "transducer") An abstract machine consisting of a set of states (including the initial state), a set of input events, a set of output events, and a state transition function. The function takes the current state and an input event and returns the new set of output events and the next state. Some states may be designated as "terminal states". The state machine can also be viewed as a function which maps an ordered sequence of input events into a corresponding sequence of (sets of) output events. A deterministic FSM (DFA) is one where the next state is uniquely determinied by a single input event. The next state of a nondeterministic FSM (NFA) depends not only on the current input event, but also on an arbitrary number of subsequent input events. Until these subsequent events occur it is not possible to determine which state the machine is in. It is possible to automatically translate any nondeterministic FSM into a deterministic one which will produce the same output given the same input. Each state in the DFA represents the set of states the NFA might be in at a given time. In a probabilistic FSM [proper name?], there is a predetermined probability of each next state given the current state and input (compare Markov chain). The terms "acceptor" and "transducer" are used particularly in language theory where automata are often considered as abstract machines capable of recognising a language (certain sequences of input events). An acceptor has a single Boolean output and accepts or rejects the input sequence by outputting true or false respectively, whereas a transducer translates the input into a sequence of output events. FSMs are used in computability theory and in some practical applications such as regular expressions and digital logic design. See also state transition diagram, Turing Machine. 1
- noun acceptor A person or thing that accepts something, in particular. 1
- abbreviation ACCEPTOR accepter. 1
- noun acceptor Finance. a person who accepts a draft or bill of exchange, especially the drawee who signs the draft or bill, confirming a willingness to pay it when due. 1
- noun acceptor Also called acceptor atom, acceptor impurity. Physics. an atom of impurity in a semiconducting crystal such that the atom can capture an electron, creating a hole in a filled electron shell and thereby changing the electric conductivity of the crystal. 1
- noun acceptor Chemistry. an atom, ion, group of atoms, or compound that combines with, or accepts, another entity, thereby profoundly affecting physical and chemical properties: electron acceptor; water acceptor. 1
- noun acceptor One who accepts. 0
- noun acceptor (law, commerce) One who accepts a draft or a bill of exchange; a drawee after he has accepted. 0
- noun acceptor (chemistry) An atom or molecule which can accept an electron to form a chemical bond. 0
- noun acceptor (biochemistry) A transfer RNA molecule that can accept a specific amino acid. 0
