WebFinite automata can be represented by input tape and finite control. Input tape: It is a linear tape having some number of cells. Each input symbol is placed in each cell. Finite control: The finite control decides the next state on receiving particular input from input tape. WebIn computer science, more specifically in automata and formal language theory, nested words are a concept proposed by Alur and Madhusudan as a joint generalization of words, as traditionally used for modelling linearly ordered structures, and of ordered unranked trees, as traditionally used for modelling hierarchical structures.Finite-state acceptors for nested …

WebNote that the only thing you need to remember is the first symbols. Thus, finite memory is sufficient; the language is regular. See vonbrand's answer. When you construct automata, note the following rules of thumb: You need a starting state. If your language is not empty, you need (reachable) accepting states.
