Linear Bounded Automata(LBA) We cannot increase power of Turing Machine by providing some options like 'STAY', '2 Read/Write Head' etc. Definition A Turing machine that uses only the tape space occupied by the input is called a linear-bounded automaton (LBA). 2. Many of them are also animated. linear bounded automata (lbas) are the same as turing machines with one difference:. A linear bounded automaton (LBA) is a TM where the tape head cannot move othe portion of the tape containing the input.
