I want to learn about nested stack automata. However my efforts to find a suitable learning resource have so far been abortive:
- The Wikipedia article on nested stack automata is a stub.
- Alfred Aho's original paper on nested stack automata is available on ACM. However it's not free and I don't have the means to pay for it.
- I've read the paper on nested stack automata written by Robert Gilman and Michael Shapiro several times but the concept, to me, is still abstruse.
I really want to learn about nested stack automata. Hence it would be nice if somebody could explain, in a rigorous manner, how a nested stack automaton works.
In addition if you could link me to some good articles which explain nested stack automata then that would be great. Perhaps you have a soft copy of Alfred Aho's original paper on nested stack automata and are willing to share it?
