[comp.theory.cell-automata] Looking for books on automata /turing machines

paalh@eik.ii.uib.no (Paal Hellesnes (Databehandling)) (03/20/91)

I am now reading Lewis/papadimitrou "Elements of the theory of
computation" (prentice-hall 1981). Is there anybody who knows books who
covers basically the
same subject? (automata, context free grammars, turing machines, my
recursive functions, uncomptability and NP-complete problems on an
undergraduate/graduate level)

 
Thanks .
