Description: OpenNWA: A Nested-Word Automaton Library. 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.
