Thu, 21 Jul 2011 21:29:10 +0200 blanchet make "concealed" lambda translation sound
Wed, 20 Jul 2011 23:47:27 +0200 blanchet use a more robust naming convention for "polymorphic" frees -- the check is an overapproximation but that's fine as far as soundness is concerned
Wed, 20 Jul 2011 00:37:42 +0200 blanchet pass type arguments to lambda-lifted Frees, to account for polymorphism
Wed, 20 Jul 2011 00:37:42 +0200 blanchet generate slightly less type information -- this should be sound since type arguments should keep things cleanly apart
Wed, 20 Jul 2011 00:37:42 +0200 blanchet avoid calling "Term.is_first_order" (indirectly) on a term with loose de Bruijns -- this is not necessary anyway because of the Abs check in "simple_translate_lambdas"
Sun, 17 Jul 2011 14:21:19 +0200 blanchet fixed lambda-liftg: must ensure the formulas are in close form
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)

Thu, 14 Jul 2011 16:50:05 +0200 blanchet move lambda translation option from ATP to Sledgehammer, to avoid accidentally breaking Metis (its reconstruction code can only deal with combinators)

Tue, 05 Jul 2011 17:09:59 +0100 nik add support for lambdas in TPTP THF generator + killed an unsound type encoding (because the monotonicity calculus assumes first-order)
Fri, 01 Jul 2011 15:53:38 +0200 blanchet further repair "mangled_tags", now that tags are also mangled
Fri, 01 Jul 2011 15:53:38 +0200 blanchet renamed "type_sys" to "type_enc", which is more accurate
Fri, 01 Jul 2011 15:53:37 +0200 blanchet cleaner handling of higher-order simple types, so that it's also possible to use first-order simple types with LEO-II and company
Fri, 01 Jul 2011 15:53:37 +0200 blanchet mangle "ti" tags
Fri, 01 Jul 2011 15:53:37 +0200 blanchet tuning
