This contribution presents reducing variant of the deep pushdown automata.
Deep pushdown automata is a new generalization of the classical pushdown
automata.
The basic idea of the modification consists of allowing these automata to access
more deeper parts of pushdown
and reducing strings to non-input symbols in the pushdown.
It works similarly to bottom-up analysis simulation of context-free grammars in
the classical pushdown automata
except it reads the input from the right to the left.
Further, this paper presents results concerning the equivalence of reducing deep
pushdown automata with n-limited state grammars
and infinite hierarchy of language families based on that and one open problem.
