got rid of one "sym_table" in "prepare_atp_problem" now that proxies are always handled first, and tuned accordingly
2011-05-01, by blanchet
drop "fequal" type args for unmangled type systems
2011-05-01, by blanchet
recognize more SystemOnTPTP errors
2011-05-01, by 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
2011-05-01, by blanchet
make sure that fequal keeps its type arguments for mangled type systems
2011-05-01, by blanchet
no needless "fequal" proxies if "explicit_apply" is set + always have readable names
2011-05-01, by blanchet
shorten readable names -- they can get really long with monomorphization, which actually slows down the ATPs
2011-05-01, by blanchet
avoid Type.TYPE_MATCH exception for "True_or_False" for "If"
2011-05-01, by blanchet
proper handling of partially applied proxy symbols
2011-05-01, by blanchet
make the problems a bit lighter by getting rid of bound quantifiers for monomorphized constants, since these always have the same return type
2011-05-01, by blanchet

2011-05-01, by blanchet

2011-05-01, by blanchet

2011-05-01, by blanchet
minor cleanup
2011-05-01, by blanchet
reimplemented the hAPP introduction code so that it's done earlier, when the types are still available
2011-05-01, by blanchet
declare TFF types so that SNARK can be used with types
2011-05-01, by 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
2011-05-01, by blanchet
move type declarations to the front, for TFF-compliance
2011-05-01, by blanchet
use postfix syntax for mangled types, for consistency with unmangled
2011-05-01, by blanchet
generate typing for "hBOOL" in "Many_Typed" mode + tuning
2011-05-01, by 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)
2011-05-01, by blanchet
improve version handling -- prefer versions of ToFoF, SInE, and SNARK that are known to work
2011-05-01, by blanchet
unprefix evil "fof_" prefix inserted by ToFoF
2011-05-01, by blanchet
added support for ToFoF prover for experimenting with the TPTP TFF (typed first-order) format
2011-05-01, by blanchet
fake type declarations for full-type args and mangled type encodings, so that type assumptions can be discharged
2011-05-01, by blanchet
generate TFF type declarations in typed mode
2011-05-01, by blanchet
no point in keeping indices in Sledgehammer readable var names, since these are disambiguated anyway
2011-05-01, by blanchet
added more rudimentary type support to Sledgehammer's ATP encoding
2011-05-01, by blanchet
fixed type of ATP quantifier types (sic)
2011-05-01, by blanchet
added "useful_info" argument to ATP formulas -- this will probably be useful later to specify intro, simp, elim to SPASS
2011-05-01, by blanchet
added support for TFF type declarations
2011-05-01, by blanchet
reintroduced constructor for formulas, and automatically detect which logic to use (TFF or FOF) to avoid clutter
2011-05-01, by blanchet
added room for types in ATP quantifiers
2011-05-01, by blanchet
distinguish FOF and TFF (typed first-order) in ATP abstract syntax tree
2011-05-01, by blanchet
remove experimental feature ("risky overload")
2011-05-01, by blanchet
added (without implementation yet) new type encodings for Sledgehammer/ATP
2011-05-01, by blanchet
close ATP formulas universally earlier, so that we can add type predicates
2011-05-01, by blanchet
get rid of "explicit_forall" prover-specific option, even if that means some clutter -- foralls will be necessary to attach types to variables
