Single letter languages accepted by alternating and probabilistic pushdown automata
We consider way k tape alternating pushdown automata k apa and way k tape alternating nite automata k afa We say that an alternating automaton accepts a language L with f n bounded maximal respectively minimal leaf size if arbitrary re spectively at least one accepting tree for any w L has no more than f jwj leaves The main results of the article are the following For way k tape alternating cou...
متن کاملLanguages Accepted by Integer Weighted Finite Automata
We study the family of languages accepted by the integer weighted nite automata. Especially the closure properties of this family are investigated.
متن کاملPushdown Automata and Context Free Languages , Part 5 Richard Cole
Proof: The result is easily confirmed by strong induction on h. Recall that the height of the tree is the length, in edges, of the longest root to leaf path. The base case, h = 1, occurs with a tree of two nodes, the root and a leaf child. Here, w is the one terminal character labeling the leaf, so |w| = 1 = 2h−1; thus the claim is true in this case. Suppose that the result is true for trees of...
متن کاملSemilinearity and Context-Freeness of Languages Accepted by Valence Automata
Valence automata are a generalization of various models of automata with storage. Here, each edge carries, in addition to an input word, an element of a monoid. A computation is considered valid if multiplying the monoid elements on the visited edges yields the identity element. By choosing suitable monoids, a variety of automata models can be obtained as special valence automata. This work is ...
متن کاملHyperedge Replacement Languages and Pushdown Automata
In this paper we are studying the relations between generated and accepted hyperedge replacement languages. In context freeness of hyperedge replacement grammars we can transform each grammar into an equivalent one in Greibach Normal Form (HRGNF). In order to create a pushdown automata for hyperedge replacement languages (PDAH) we build an algorithm to transform the planar structure of a hyperg...
