Member Function Documentation

void spot::couvreur99_check_result::accepting_cycle  )  [protected]
 

Called by accepting_run() to find a cycle which traverses all acceptance conditions in the accepted SCC.

virtual tgba_run* spot::couvreur99_check_result::accepting_run  )  [virtual]
 

Return a run accepted by the automata passed to the emptiness check.

This method might actually compute the acceptance run. (Not all emptiness check algorithms actually produce a counter-example as a side-effect of checking emptiness, some need some post-processing.)

This can also return 0 if the emptiness check algorithm cannot produce a counter example (that does not mean there is no counter-example; the mere existence of an instance of this class asserts the existence of a counter-example).

Reimplemented from spot::emptiness_check_result.

virtual unsigned spot::couvreur99_check_result::acss_states  )  const [virtual]
 

Number of states in the search space for the accepting cycle.

Implements spot::acss_statistics.

unsigned spot::ars_statistics::ars_prefix_states  )  const [inline, inherited]
 

const tgba* spot::emptiness_check_result::automaton  )  const [inline, inherited]

Return the options parametrizing how the accepting run is computed.

virtual void spot::emptiness_check_result::options_updated const option_map old  )  [protected, virtual, inherited]
 

Notify option updates.

const char* spot::emptiness_check_result::parse_options char *  options  )  [inherited]
 

Modify the algorithm options.

virtual const unsigned_statistics* spot::emptiness_check_result::statistics  )  const [virtual, inherited]
 

Return statistics, if available.
