Abstract

We present the second generation of the tool Seminator that transforms transition-based generalized Büchi automata (TGBAs) into equivalent semi-deterministic automata. The tool has been extended with numerous optimizations and produces considerably smaller automata than its first version. In connection with the state-of-the-art LTL to TGBAs translator Spot, Seminator 2 produces smaller (on average) semi-deterministic automata than the direct LTL to semi-deterministic automata translator ltl2ldgba of the Owl library. FurtherSeminator 2 has been extended with an improved NCSB complementation procedure for semi-deterministic automataproviding a new way to complement automata that is competitive with state-of-the-art complementation tools.
