Mon, 02 May 2011 01:05:24 +0200 blanchet tuning

Sun, 01 May 2011 22:36:58 +0200 blanchet use "metis", not "metisFT", to reconstruct proofs found in fully-typed mode -- "metisFT" is just too slow...
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 18:57:45 +0200 blanchet minor doc fixes
Sun, 01 May 2011 18:52:38 +0200 blanchet adapt to new type system names
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 take "partial_types" option with a grain of salt
Sun, 01 May 2011 18:37:25 +0200 blanchet fixed SPASS fact offset calculation and report unexpected unsound proofs with so-called sound encodings
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 pick up GaveUp error on SystemOnTPTP
Sun, 01 May 2011 18:37:25 +0200 blanchet avoid trailing digits for SNARK (type) names -- grr...
Sun, 01 May 2011 18:37:25 +0200 blanchet document new type system syntax
Sun, 01 May 2011 18:37:25 +0200 blanchet use ! for mildly unsound and !! for very unsound encodings
Sun, 01 May 2011 18:37:25 +0200 blanchet use new type system syntax
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 define type system in ATP module so that ATPs can suggest a type system
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 recognize more SystemOnTPTP errors
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 shorten readable names -- they can get really long with monomorphization, which actually slows down the ATPs
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 better known failure recognition for ToFoF-E
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 more higher-order tests for Sledgehammer/ATP

Sun, 01 May 2011 18:37:24 +0200 blanchet added a hint to Metis errors suggesting metisFT -- it sometimes work
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 fixed parsing of not in ATP proofs (e.g. ~x | y is (~x) | y, not ~(x | y))
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 improve version handling -- prefer versions of ToFoF, SInE, and SNARK that are known to work
