Pushdown Automata

Pushdown Automata. There are context-free languages that are not regular. Finite automata cannot recognize all context-free languages. Pushdown Automata. {a, b}* is regular. {a k b k | k is a constant} is regular. {a n b n | n ? 0 } is not regular. Finite Automata. Input file.

CS355 - Theory of Computation. Context-Free Languages. Last Time. Is L = {0 i x | i ? 0, x {0,1}* and |x| ? i} regular? Is L = {0 i | i is prime} regular?. Context-Free Languages. Context-Free Languages (CFL) are described using Context-Free Grammars (CFG).
