Thu, 12 May 2011 15:29:19 +0200 blanchet improve detection of quantifications over dangerous types by leveraging "is_type_surely_finite" predicate and added "prop" to the list of surely finite types

Thu, 12 May 2011 15:29:18 +0200 blanchet added "max_mono_instances" option to Sledgehammer and renamed old "monomorphize_limit" option

Tue, 03 May 2011 01:04:03 +0200 blanchet no need to generate fact numbers for polymorphic type systems -- this confuses the TPTP exporter

Mon, 02 May 2011 22:52:15 +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 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 18:37:24 +0200 blanchet make sure the minimizer monomorphizes when it should
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 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
