Human Pass
- 14 of 17 problems solved by expert pruning of the background knowledge
(could probably be automated for large sets of problems)
- 3 problems could not be solved
- A background axiom was omitted by the MPTP translation
- Probably countersatisfiable (not confirmed yet)
- All from one challenge problem
- Easily solved after addition of the missing background axiom
- Final result:
- 251 challenge problems verified
- 1 challenge problem probably countersatisfiable
(verified after adding the missing background axiom)
- Found a rare case of incompleteness of the MPTP translation algorithm
