Multi-Head Finite Automata: Characterizations, Concepts and Open Problems
Markus Holzer, Martin Kutrib, Andreas Malcher
Multi-head finite automata were introduced in (Rabin, 1964) and (Rosenberg, 1966). Since that time, a vast literature on computational and descriptional complexity issues on multi-…

Descriptional complexity of bounded context-free languages
Andreas Malcher, Giovanni Pighizzini
Finite-turn pushdown automata (PDA) are investigated concerning their descriptional complexity. It is known that they accept exactly the class of ultralinear context-free languages…
