Sun, 13 May 2012 16:31:01 +0200 blanchet eta-reduce definition-like equations for THF provers; Satallax in particular seems to love that
Sun, 13 May 2012 16:31:01 +0200 blanchet get rid of "conj_sym_kind" -- most interesting provers now have built-in sorts, and for the others (e.g. E) "Hypothesis" isn't too bad a default
Sun, 13 May 2012 16:31:01 +0200 blanchet extend ATP data structure to avoid having to perform ((non-)capture avoiding) beta reduction -- fixes a bug in the THF translation of "is_measure.simps"

Wed, 25 Apr 2012 22:00:33 +0200 blanchet don't extensionalize formulas for higher-order provers -- Satallax in particular will only expand definitions of the form "constant = ..."
Wed, 25 Apr 2012 22:00:33 +0200 blanchet don't use the native choice operator if the type encoding isn't higher-order

Tue, 20 Mar 2012 13:53:09 +0100 blanchet remove two options that were found to play hardly any role
Tue, 20 Mar 2012 10:06:35 +0100 blanchet added "metis_advisory_simp" option to orient as many equations as possible in Metis the right way (cf. "More SPASS with Isabelle")

Mon, 27 Feb 2012 16:56:25 +0100 wenzelm more explicit Long_Name operations (NB: analyzing qualifiers is inherently fragile);

Fri, 24 Feb 2012 11:23:34 +0100 blanchet general solution to the arity bug that occasionally plagues Sledgehammer -- short story, lots of things go kaputt when a polymorphic symbol's arity in the translation is higher than the arity of the fully polymorphic HOL constant
Fri, 24 Feb 2012 11:23:32 +0100 blanchet fixed arity bug with "If" helpers for "If" that returns a function

Thu, 02 Feb 2012 15:14:18 +0100 blanchet change 9ce354a77908 wasn't quite right -- here's an improvement
Thu, 02 Feb 2012 12:42:05 +0100 blanchet don't introduce new symbols in helpers -- makes problems unprovable
