Method Detail

getProverName

public ProverName getProverName()

Description copied from interface: _Prover

Returns an object describing the detailed name of the prover.

Specified by:

getProverName in interface _Prover

Returns:

the detailed name of the prover.

getStrategy

public _Strategy getStrategy()

Description copied from interface: _Prover

Returns the strategy used by this prover.

Specified by:

getStrategy in interface _Prover

Returns:

the strategy.

statusFor

public ProvabilityStatus statusFor(ProofSearchResult result)

Description copied from interface: _Prover

Returns the provability status corresponding to the specified proof-search result. In a usual calculus a successful proof-search (result ProofSearchResult.SUCCESS) corresponds to a provable problem (status ProvabilityStatus.PROVABLE), while a failed proof-search (result ProofSearchResult.FAILURE) corresponds to an unprovable problem (status ProvabilityStatus.UNPROVABLE). On the other hand, in a calculus for unprovability a successful proof-search corresponds to an unprovable formula, while a failed proof-search corresponds to a provable formula (status ProvabilityStatus.PROVABLE).

Specified by:

statusFor in interface _Prover

Parameters:

result - the result of the proof-search.

Returns:

the corresponding provability status.
