    Description copied from interface: EquivalenceOracle
    
    Searches for a counterexample disproving the subjected hypothesis. A counterexample is query which, when performed on the SUL, yields a different output than what was predicted by the hypothesis. If no counterexample could be found (this does not necessarily mean that none exists), null is returned.
    
    Specified by:
    
    findCounterExample in interface EquivalenceOracle<A extends DetSuffixOutputAutomaton<?,I,?,Word<O>>,I,O>
    
    Parameters:
    
    hypothesis - the conjecture
    
    inputs - the set of inputs to consider, this should be a subset of the input alphabet of the provided hypothesis
    
    Returns:
    
    a query exposing different behavior, or null if no counterexample could be found. In case a non-null value is returned, the output field in the DefaultQuery contains the SUL output for the respective query.
