GOAL for Games, Omega-Automata, and Logics
Abstract:
¡@
GOAL is a graphical interactive tool for games,
£s-automata, and logics. Since 2011, it has been migrated to the second
generation, which is a complete redesign with an extensible architecture, many
enhancements to existing functions, and new features.
The extensible architecture allows easy integration of third-party plugins. The
enhancements provide more automata conversion, complementation, simplification,
and testing algorithms, translation of full QPTL formulae, and better automata
navigation with more layout algorithms and utility functions. The new features
include game solving, manipulation of two-way alternating automata, translation
of ACTL formulae and £s-regular expressions, test of language star-freeness,
classification of £s-regular languages into the temporal hierarchy of Manna and
Pnueli, and a script interpreter.
