findCounterExample
public @Nullable DefaultQuery<I,Word<O>> findCounterExample(SPMM<?,I,?,O> hypothesis, Collection<? extends I> inputs)
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 interfaceEquivalenceOracle<SPMM<?,I,?,O>,I,Word<O>>
- Parameters:
hypothesis
- the conjectureinputs
- 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 theDefaultQuery
contains the SUL output for the respective query.
