Mon, 22 Aug 2011 15:02:45 +0200	blanchet	reintroduced slightly unsound optimization taken out in 717880e98e6b, but only if "sound" is false	file \| diff \| annotate
Sun, 17 Jul 2011 14:21:19 +0200	blanchet	fixed lambda-liftg: must ensure the formulas are in close form	file \| diff \| annotate
Sun, 17 Jul 2011 14:12:45 +0200	blanchet	ensure that the lambda translation procedure is called only once with all the facts, which is necessary for soundness of lambda-lifting (freshness of new names)	file \| diff \| annotate
Thu, 14 Jul 2011 16:50:05 +0200	blanchet	added option to control which lambda translation to use (for experiments)	file \| diff \| annotate
Mon, 27 Jun 2011 14:56:28 +0200	blanchet	added "sound" option to force Sledgehammer to be pedantically sound	file \| diff \| annotate
Thu, 16 Jun 2011 13:50:35 +0200	blanchet	gave up an optimization that sometimes lead to unsound proofs -- in short, facts talking about a schematic type variable can encode a cardinality constraint and be consistent with HOL, e.g. "card (UNIV::?'a set) = 1 ==> ALL x y. x = y"	file \| diff \| annotate
Mon, 06 Jun 2011 20:36:35 +0200	blanchet	gracefully handle the case where a constant is partially or not instantiated at all, as may happen when reconstructing Metis proofs for polymorphic type encodings	file \| diff \| annotate
Tue, 31 May 2011 16:38:36 +0200	blanchet	first step in sharing more code between ATP and Metis translation	file \| diff \| annotate
