Detailed Description

Compute a counter example from a spot::couvreur99_check_status.

Member Function Documentation

accepting_cycle()

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.

accepting_run()

virtual twa_run_ptr spot::couvreur99_check_result::accepting_run ( )

overridevirtual

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.

acss_states()

virtual unsigned spot::couvreur99_check_result::acss_states ( ) const

overridevirtual

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

Implements spot::acss_statistics.

automaton()

const const_twa_ptr & spot::emptiness_check_result::automaton ( ) const

inlineinherited

The automaton on which an accepting_run() was found.

References a_.

options()

const option_map & spot::emptiness_check_result::options ( ) const

inlineinherited

Return the options parameterizing how the accepting run is computed.

options_updated()

virtual void spot::emptiness_check_result::options_updated ( const option_map & old )

protectedvirtualinherited

Notify option updates.

parse_options()

const char * spot::emptiness_check_result::parse_options ( char * options )

inherited

Modify the algorithm options.

References options().

statistics()

virtual const unsigned_statistics * spot::emptiness_check_result::statistics ( ) const

virtualinherited

Return statistics, if available.
