|
file | diff | annotate |
| Thu, 13 May 2010 21:17:09 +0200 |
the_classrel/the_arity: avoid Thm.transfer for proofterm version -- theory might already have become stale within the proof_body future;

tuned aritiy completion -- slightly less intermediate data structures;
|
file | diff | annotate |
| Tue, 27 Apr 2010 14:41:27 +0200 |
clarified proven results: store thm only and retrieve proof later via Thm.proof_of (this may also impact parallelism, because internal join_proofs is deferred);
