Theory of Computation. What is possible to compute?. We can prove that there are some problems computers cannot solve. There are some problems computers can theoretically solve, but are intractable (would take too long to compute to be practical). Great Theoretical Ideas In Computer Science. Anupam. Gupta.

Finite-state automata (deterministic vs. non-deterministic). A deterministic finite automaton (DFA) is a five-tuple A = (Q, . , , q. 0,. F) where. Q is a finite set of . states.  is a finite set of . input symbols.  is a function : Q   Q called . Introduce finite state automata.
