WebA linear bounded automaton is a nondeterministic Turing machine with a finite amount of tape. The amount of tape the Turing machine may use should be proportional to the input size. Some formulations use tape size equal to input size, which I find too restrictive, but the two models turn out to be equivalent in power.

Some applications of modern automata include robotics applications, spell checkers and text editors, use of AI, and genetic programming. Automata is the study and understanding of abstract machines.

WebA linear bounded automaton (LBA) is an abstract machine that would be identical to a Turing machine, except that during a computation with given input its tape-head is not allowed to move outside a bounded region of its infinite tape, the number of accessible tape-cells being a linear function of the input-size.The tape itself has infinite length in order to … WebAn automaton (automata in plural) is an abstract self-propelled computing device which follows a predetermined sequence of operations automatically. An automaton with a finite number of states is called a Finite Automaton (FA) or Finite-State Machine (FSM).
