OpenNWA: A Nested-Word Automaton Library
Driscoll, Evan and Thakur, Aditya V. and Reps, Thomas W.24th International Conference on Computer Aided Verification (CAV), 2012
Nested-word automata (NWAs) are a language formalism that helps bridge the gap between finite-state automata and pushdown automata. NWAs can express some context-free properties, such as parenthesis matching, yet retain all the desirable closure characteristics of finite-state automata.
This paper describes OpenNWA, a C++ library for working with NWAs. The library provides the expected automata-theoretic operations, such as intersection, determinization, and complementation. It is packaged with WALi – the Weighted Automaton Library – and interoperates closely with the weighted pushdown system portions of WALi.
