Thu, 14 Jul 2011 15:14:38 +0200 blanchet fix subtle type inference bug in Metis -- different occurrences of the same Skolem might need to be typed differently, using paramify_vars overconstraints the typing problem
Fri, 01 Jul 2011 15:53:38 +0200 blanchet renamed "type_sys" to "type_enc", which is more accurate
Mon, 27 Jun 2011 14:56:28 +0200 blanchet added "sound" option to force Sledgehammer to be pedantically sound
Tue, 21 Jun 2011 17:17:39 +0200 blanchet remove historical bloat -- another benefit of merging Metis's and Sledgehammer's translations
Thu, 09 Jun 2011 00:16:28 +0200 blanchet cleaner fact freshening, which also works in corner cases, e.g. if two backquoted facts have the same name (but have different variable indices)
Wed, 08 Jun 2011 16:20:19 +0200 blanchet pass Metis facts and negated conjecture as facts, with (almost) correctly set localities, so that the correct encoding is used for nonmonotonic occurrences of infinite types
Wed, 08 Jun 2011 08:47:43 +0200 blanchet removed yet another hack in "make_metis" script -- respect opacity of "Metis_Name.name"
Wed, 08 Jun 2011 08:47:43 +0200 blanchet killed "explicit_apply" option in Sledgehammer -- the "smart" default is about as lightweight as "false" and just as complete as "true"
Tue, 07 Jun 2011 14:17:35 +0200 blanchet more suitable implementation of "schematic_consts_of" for monomorphizer, for ATPs
Tue, 07 Jun 2011 10:46:09 +0200 blanchet removed "verbose" option -- there won't be any verbosity in there, according to Sascha (yeah)
Tue, 07 Jun 2011 10:43:18 +0200 blanchet nicely thread monomorphism verbosity in Metis and Sledgehammer
Tue, 07 Jun 2011 07:06:24 +0200 blanchet renamed ML function

Mon, 06 Jun 2011 20:36:35 +0200 blanchet don't pass "~ " to new Metis
Mon, 06 Jun 2011 20:36:34 +0200 blanchet clean up unnecessary machinery -- helpers work also with monomorphic type encodings
Mon, 06 Jun 2011 20:36:34 +0200 blanchet added support for helpers in new Metis, so far only for polymorphic type encodings
Wed, 01 Jun 2011 10:29:43 +0200 blanchet ensured monomorphized facts have normalized zero var indexes, so that "find_var" doesn't fail later on
Wed, 01 Jun 2011 10:29:43 +0200 blanchet implemented missing hAPP and ti cases of new path finder
Wed, 01 Jun 2011 10:29:43 +0200 blanchet support lightweight tags in new Metis
Wed, 01 Jun 2011 10:29:43 +0200 blanchet tuned names
Wed, 01 Jun 2011 10:29:43 +0200 blanchet distinguish different kinds of typing informations in the fact name
Tue, 31 May 2011 16:38:36 +0200 blanchet monomorphize in the new Metis if the type system calls for it
Tue, 31 May 2011 16:38:36 +0200 blanchet fixed new path finder for type information tag
Tue, 31 May 2011 16:38:36 +0200 blanchet use ":" for type information (looks good in Metis's output) and handle it in new path finder
Tue, 31 May 2011 16:38:36 +0200 blanchet tuned name
Tue, 31 May 2011 16:38:36 +0200 blanchet tuned name
Tue, 31 May 2011 16:38:36 +0200 blanchet parse optional type system specification

Tue, 31 May 2011 16:38:36 +0200 blanchet tuning

Fri, 20 May 2011 17:16:13 +0200 blanchet further improvements to "poly_{preds,tags}_{bang,query}" -- better solution to the combinator problem + make sure type assumptions can be discharged
Fri, 20 May 2011 17:16:13 +0200 blanchet prevent unsound combinator proofs in partially typed polymorphic type systems
Fri, 20 May 2011 12:47:58 +0200 blanchet tuning

Tue, 03 May 2011 14:23:40 +0200 blanchet reintroduce this idea of running "metisFT" after a failed "metis" -- I took it out in e85ce10cef1a because I couldn't think of a reasonable use case, but now that ATPs use sound encodings and include dangerous facts (e.g. True_or_False) it makes more sense than ever to run "metisFT" after "metis"
Sun, 01 May 2011 18:37:25 +0200 blanchet drop "fequal" type args for unmangled type systems
Sun, 01 May 2011 18:37:25 +0200 blanchet cleanup proxification/unproxification and make sure that "num_atp_type_args" is called on the proxy in the reconstruction code, since "c_fequal" has one type arg but the unproxified equal has 0
Sun, 01 May 2011 18:37:24 +0200 blanchet improve helper type instantiation code
