There have been several recent suggestions for tableau systems for deciding
satisfiability in the practically important branching time temporal logic known
as CTL*. In this paper we present a streamlined and more traditional tableau
approach built upon the author's earlier theoretical work.
Soundness and completeness results are proved. A prototype implementation
demonstrates the significantly improved performance of the new approach on a
range of test formulas. We also see that it compares favourably to state of the
art, game and automata based decision procedures.Comment: In Proceedings GandALF 2013, arXiv:1307.416
