Method Summary

Modifier and Type	Method and Description
ProverName	getProverName() Returns an object describing the detailed name of the prover.
_Strategy	getStrategy() Returns the strategy used by this prover.
ProvabilityStatus	statusFor(ProofSearchResult result) Returns the provability status corresponding to the specified proof-search result.

Method Detail

getProverName

ProverName getProverName()

Returns an object describing the detailed name of the prover.

Returns:

the detailed name of the prover.

getStrategy

_Strategy getStrategy()

Returns the strategy used by this prover.

Returns:

the strategy.

statusFor

ProvabilityStatus statusFor(ProofSearchResult result)

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).

Parameters:

result - the result of the proof-search.

Returns:

the corresponding provability status.
