/// \brief A Transition-based Generalized Testing Automaton (TGTA).
|
|
///
|
|
/// Transition-based Generalized Testing Automaton (TGTA) is a new
|
|
/// kind of automaton that combines features from both TA and TGBA.
|
|
/// From TA, we take the idea of labeling transitions with
|
|
/// changesets, however we remove the use of livelock-acceptance
|
|
/// (because it may require a two-pass emptiness check), and the
|
|
/// implicit stuttering. From TGBA, we inherit the use of
|
|
/// transition-based generalized acceptance conditions. The
|
|
/// resulting Chimera, which we call "Transition-based Generalized
|
|
/// Testing Automaton" (TGTA), accepts only stuttering-insensitive
|
|
/// languages like TA, and inherits advantages from both TA and
|
|
/// TGBA: it has a simple one-pass emptiness-check procedure (the
|
|
/// same as algorithm the one for TGBA), and can benefit from
|
|
/// reductions based on the stuttering of the properties pretty much
|
|
/// like a TA. Livelock acceptance states, which are no longer
|
|
/// supported are emulated using states with a Büchi accepting
|
|
/// self-loop labeled by empty changeset.
|
|
///
|
|
/// Browsing such automaton can be achieved using two functions:
|
|
/// \c get_initial_state and \c
|
|
/// succ_iter. The former returns the initial state(s) while the latter lists
|
|
/// the successor states of any state. A second implementation of \c succ_iter
|
|
/// returns only the successors reached through a changeset passed as
|
|
/// a parameter.
|
|
///
|
|
/// Note that although this is a transition-based automata,
|
|
/// we never represent transitions! Transition informations are
|
|
/// obtained by querying the iterator over the successors of
|
|
/// a state.
