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 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 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 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

Sun, 01 May 2011 18:37:24 +0200 blanchet fixed type of ATP quantifier types (sic)
Sun, 01 May 2011 18:37:24 +0200 blanchet added "useful_info" argument to ATP formulas -- this will probably be useful later to specify intro, simp, elim to SPASS
Sun, 01 May 2011 18:37:24 +0200 blanchet added support for TFF type declarations
Sun, 01 May 2011 18:37:24 +0200 blanchet reintroduced constructor for formulas, and automatically detect which logic to use (TFF or FOF) to avoid clutter
Sun, 01 May 2011 18:37:24 +0200 blanchet added room for types in ATP quantifiers
Sun, 01 May 2011 18:37:24 +0200 blanchet distinguish FOF and TFF (typed first-order) in ATP abstract syntax tree

Sun, 01 May 2011 18:37:23 +0200 blanchet close ATP formulas universally earlier, so that we can add type predicates
Sun, 01 May 2011 18:37:23 +0200 blanchet get rid of "explicit_forall" prover-specific option, even if that means some clutter -- foralls will be necessary to attach types to variables
Sun, 01 May 2011 18:37:23 +0200 blanchet renamings
Thu, 21 Apr 2011 22:18:28 +0200 blanchet detect some unsound proofs before showing them to the user

Thu, 14 Apr 2011 11:24:05 +0200 blanchet correctly handle TFrees that occur in (local) facts -- Metis did the right thing here but Sledgehammer was incorrectly generating spurious preconditions such as "dense_linorder(t_a)"
Tue, 05 Apr 2011 11:39:48 +0200 blanchet renamed "const_args" option value to "args"
