TY - JOUR ID - 955038 AU - Csuhaj-Varjú, Erzsebet - Masopust, Tomáš - Vaszil, Gyorgy PY - 2011 TI - Blackhole Pushdown Automata JF - Fundamenta Informaticae VL - 112 IS - 2-3 SP - 137-156 EP - 137-156 PB - IOS Press, Nizozemí SN - 01692968 KW - Pushdown automaton, regulation, computational power. UR - http://dx.doi.org/10.3233/FI-2011-584 N2 - We introduce and investigate blackhole pushdown automata, variants of pushdown automata, where a string can always be pushed to the pushdown, but only a given depth of the pushdown content is remembered (the rest of the pushdown content is either canceled or becomes inaccessible). We also study blackhole variants of regulated pushdown automata, where the automaton in some distinguished states checks the form of its pushdown content against a given control language. We present characterizations of several language families in terms of these constructs. ER -
