Automata - Finals

A TM accepts language generated by ___________.

Verifies the text's syntax

Contains specific number of squares that contain a single input symbol. Strings placed is traversed from left to right

Scans each square in the input tape and reads input from the tape. Moves from left to right.

Serves as the control unit of the PDA. Decides which state the pda will move and which stack symbol it will push or pop

Temporary storage of stack symbols. Allows pda ro recognize some non regular languages.

Describes the configuration of the PDA at a given instance. It remembers tha state's information at a given instance of time.

String can be declared as accepted after the total traversal of the input string the pda enters into its final state

String can be declared as accepted by an empty stack if all the input characters, the stack is empty after reading the rightmost input character

Describes the current state

Describes the remaining/unconsumed input

Describes the stack contents (the leftmos symbol corresponds to the top of the stack and the rightmost symbol is the bottom element)

No creativity implies that each step in the calculation must be fully spelled out

The list of instructions followed must be infinite

Each individual step in the calculation must take an infinite amount of time to complete

Intermediate results may need to be calculated, so a scratch-pad area is needed

There is no need to keep track of the current step of the calculation

There must be a way to keep track of the current state of the calculation
