Thu, 05 May 2011 10:16:14 +0200 blanchet reverted 6efda6167e5d because unsound -- Vampire found a counterexample
Thu, 05 May 2011 08:03:28 +0200 blanchet I have an intuition that it's sound to omit the first type arg of an hAPP -- and this reduces the size of monomorphized problems quite a bit
Thu, 05 May 2011 02:27:02 +0200 blanchet removed unsound hAPP optimization
Thu, 05 May 2011 00:51:56 +0200 blanchet versions of ! and ? for the ASCII-challenged Mirabelle
Thu, 05 May 2011 00:22:37 +0200 blanchet smoother handling of ! and ? in type system names
Wed, 04 May 2011 23:26:20 +0200 blanchet tuning
Wed, 04 May 2011 23:18:28 +0200 blanchet documentation tuning
Wed, 04 May 2011 22:56:33 +0200 blanchet renamed "many_typed" to "simple" (as in simple types)
Wed, 04 May 2011 22:47:13 +0200 blanchet added type homogenization, whereby all (isomorphic) infinite types are mapped to the same type (to reduce the number of different predicates/TFF-types)
Wed, 04 May 2011 19:35:48 +0200 blanchet exploit inferred monotonicity
Wed, 04 May 2011 15:35:05 +0200 blanchet monotonic type inference in ATP Sledgehammer problems -- based on Claessen & al.'s CADE 2011 paper, Sect. 2.3.
Wed, 04 May 2011 11:49:46 +0200 blanchet added type annotation for SML/NJ
Wed, 04 May 2011 10:12:44 +0200 blanchet eta-expansion for SML/NJ
Tue, 03 May 2011 21:46:05 +0200 blanchet cosmetics
Tue, 03 May 2011 01:04:03 +0200 blanchet no need to generate fact numbers for polymorphic type systems -- this confuses the TPTP exporter
Tue, 03 May 2011 00:10:22 +0200 blanchet replaced some Unsynchronized.refs with Config.Ts
Mon, 02 May 2011 23:01:22 +0200 blanchet do not declare TPTP built-ins, e.g. $true
Mon, 02 May 2011 22:52:15 +0200 blanchet generate tags for simps, intros, and elims in TPTP poblems on demand
Mon, 02 May 2011 14:40:57 +0200 blanchet use strings to encode type systems in ATP module, to reduce the amount of out-of-place information and also to make it easier to print the type system used
Mon, 02 May 2011 14:28:28 +0200 blanchet cosmetics
Mon, 02 May 2011 13:52:15 +0200 blanchet make sure E type information constants are given a weight, even if they don't appear anywhere else
Sun, 01 May 2011 21:53:32 +0200 blanchet beware of polymorphic types in typed translation symbol declarations -- match alpha-equivalent types and, more importantly, prevent unsoundnesses by generating type constraints on the arguments of a polymorphic symbols (otherwise "hAPP" can be given any result type)
Sun, 01 May 2011 18:37:25 +0200 blanchet restructured type systems some more -- the old naming schemes had "argshg diff |less" and "tagshg diff |less" as equivalent and didn't support a monomorphic version of "tags"
Sun, 01 May 2011 18:37:25 +0200 blanchet close formula universally, to make SPASS happy
Sun, 01 May 2011 18:37:25 +0200 blanchet fixed embarrassing bug where conjecture and fact offsets were swapped
Sun, 01 May 2011 18:37:25 +0200 blanchet implement the new ATP type system in Sledgehammer
Sun, 01 May 2011 18:37:25 +0200 blanchet made the format (TFF or FOF) of the TPTP problem a global argument of the problem again and have the ATPs report which formats they support
Sun, 01 May 2011 18:37:25 +0200 blanchet merge symbol declarations that are type-instances of each other -- useful for type system "Args true" with monomorphization turned off
Sun, 01 May 2011 18:37:25 +0200 blanchet drop even more bound types in symbol declarations -- useful in particular for type system "Args true"
Sun, 01 May 2011 18:37:25 +0200 blanchet tuning
Sun, 01 May 2011 18:37:25 +0200 blanchet got rid of one "sym_table" in "prepare_atp_problem" now that proxies are always handled first, and tuned accordingly
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 18:37:25 +0200 blanchet make sure that fequal keeps its type arguments for mangled type systems
Sun, 01 May 2011 18:37:24 +0200 blanchet no needless "fequal" proxies if "explicit_apply" is set + always have readable names
Sun, 01 May 2011 18:37:24 +0200 blanchet avoid Type.TYPE_MATCH exception for "True_or_False" for "If"
Sun, 01 May 2011 18:37:24 +0200 blanchet proper handling of partially applied proxy symbols
Sun, 01 May 2011 18:37:24 +0200 blanchet make the problems a bit lighter by getting rid of bound quantifiers for monomorphized constants, since these always have the same return type
Sun, 01 May 2011 18:37:24 +0200 blanchet improve helper type instantiation code
Sun, 01 May 2011 18:37:24 +0200 blanchet killed needless datatype "combtyp" in Metis
Sun, 01 May 2011 18:37:24 +0200 blanchet have properly type-instantiated helper facts (combinators and If)
Sun, 01 May 2011 18:37:24 +0200 blanchet don't destroy sym table entry for special symbols such as "hAPP" if "explicit_apply" is set
Sun, 01 May 2011 18:37:24 +0200 blanchet cleaned up "explicit_apply" so that it shares most of its code path with the default mode of operation
Sun, 01 May 2011 18:37:24 +0200 blanchet fixed min-arity computation when "explicit_apply" is specified
Sun, 01 May 2011 18:37:24 +0200 blanchet fixed "tags" type encoding after latest round of changes
Sun, 01 May 2011 18:37:24 +0200 blanchet fix handling of proxies after recent drastic changes to the type encodings
Sun, 01 May 2011 18:37:24 +0200 blanchet reconstruct TFF type predicates correctly for ToFoF
Sun, 01 May 2011 18:37:24 +0200 blanchet handle special constants correctly in Isar proof reconstruction code, especially type predicates
Sun, 01 May 2011 18:37:24 +0200 blanchet make sure the minimizer monomorphizes when it should
Sun, 01 May 2011 18:37:24 +0200 blanchet fixed arity of special constants if "explicit_apply" is set
Sun, 01 May 2011 18:37:24 +0200 blanchet make sure typing fact names are unique (needed e.g. by SNARK)
Sun, 01 May 2011 18:37:24 +0200 blanchet minor cleanup
Sun, 01 May 2011 18:37:24 +0200 blanchet reimplemented the hAPP introduction code so that it's done earlier, when the types are still available
Sun, 01 May 2011 18:37:24 +0200 blanchet declare TFF types so that SNARK can be used with types
Sun, 01 May 2011 18:37:24 +0200 blanchet perform constant mangling and/or removal of its type args in an earlier phase, so that the rest of the code doesn't need to worry about it
Sun, 01 May 2011 18:37:24 +0200 blanchet move type declarations to the front, for TFF-compliance
Sun, 01 May 2011 18:37:24 +0200 blanchet use postfix syntax for mangled types, for consistency with unmangled
Sun, 01 May 2011 18:37:24 +0200 blanchet generate typing for "hBOOL" in "Many_Typed" mode + tuning
Sun, 01 May 2011 18:37:24 +0200 blanchet generate pure TFF problems -- ToFoF doesn't like mixtures of FOF and TFF, even when the two logics coincide (e.g. for ground formulas)
Sun, 01 May 2011 18:37:24 +0200 blanchet fake type declarations for full-type args and mangled type encodings, so that type assumptions can be discharged
