Automatic Learning of Subclasses of Pattern Languagesy, given an index for the language. For alphabet size of at least 4, every automatic class of erasing pattern languages is contained, for some constant ., in the class of all languages generated by patterns which contain (1) every variable only once and (2) at most . symbols after the first occurren爱管闲事 发表于 2025-3-30 23:17:22

Vector Addition System Reachability Problem: A Short Self-contained Prooff actions and a second one that tries to prove the non-reachability by enumerating Presburger formulas. In this paper we provide the first proof of the VAS reachability problem that is not based on the KLMST decomposition. The proof is based on the notion of production relations, inspired from Hausccorpus-callosum 发表于 2025-3-31 16:17:41
Finitary Languagesmata. We (a) show that the finitary languages are Σ..-complete; (b) present a complete picture of the expressive power of various classes of automata with finitary and infinitary acceptance conditions; (c) show that the languages defined by finitary parity automata exactly characterize the star-freeBALK 发表于 2025-3-31 21:05:33
