Thu, 01 Sep 2011 13:18:27 +0200 blanchet always measure time for ATPs -- auto minimization relies on it

Tue, 22 Mar 2011 17:20:54 +0100 blanchet let SMT errors through -- the main reason for keeping them quiet was that the SMT bridge used to suffer from internal bugs, but these have been fixed for some time now
Tue, 22 Mar 2011 17:20:53 +0100 blanchet make Minimizer honor "verbose" and "debug" options better

Sun, 13 Mar 2011 16:01:00 +0100 wenzelm Path.print is the official way to show file-system paths to users -- note that Path.implode often indicates violation of the abstract datatype;
Mon, 21 Feb 2011 13:59:44 +0100 blanchet exit code 127 can mean many things -- not just (and probably not) Perl missing
Mon, 21 Feb 2011 10:31:48 +0100 blanchet give more weight to Frees than to Consts in relevance filter
Thu, 10 Feb 2011 10:09:38 +0100 blanchet make minimizer verbose

Tue, 21 Dec 2010 04:33:17 +0100 blanchet proper handling of the arguments of SMT builtins -- for numerals, ignore the arguments (Pls, Bit0, Bit1, ..), for functions, consider them;
Tue, 21 Dec 2010 03:56:51 +0100 blanchet added "smt_triggers" option to experiment with triggers in Sledgehammer;
Mon, 20 Dec 2010 14:55:24 +0100 blanchet run SPASS and Vampire in SOS mode only if >= 50 facts are passed -- otherwise we are probably minimizing and then it's better if the prover is run only once with a full strategy
Mon, 20 Dec 2010 14:09:45 +0100 blanchet remove spurious line
Mon, 20 Dec 2010 12:12:35 +0100 blanchet optionally supply constant weights to E -- turned off by default until properly parameterized
Fri, 17 Dec 2010 22:15:08 +0100 blanchet more precise error messages in "verbose" (or "debug") mode, following this morning's permission debacle
Fri, 17 Dec 2010 21:31:19 +0100 blanchet put the SMT weights back where they belong, so that they're also used by Mirabelle
Fri, 17 Dec 2010 15:30:43 +0100 blanchet run the SMT relevance filter only once, then run the normalization/monomorphization code once _per class_ of SMT solvers
Fri, 17 Dec 2010 12:10:08 +0100 blanchet make timeout part of the SMT filter's tail
Fri, 17 Dec 2010 12:02:46 +0100 blanchet split "smt_filter" into head and tail
Fri, 17 Dec 2010 09:56:04 +0100 blanchet trap one more Z3 error
Fri, 17 Dec 2010 00:27:40 +0100 blanchet more precise/correct SMT error handling
Thu, 16 Dec 2010 22:45:02 +0100 blanchet discriminate SMT errors a bit better
Thu, 16 Dec 2010 15:46:54 +0100 blanchet no need to do a super-duper atomization if Metis fails afterwards anyway
Thu, 16 Dec 2010 15:12:17 +0100 blanchet robustly handle SMT exceptions in Sledgehammer
Thu, 16 Dec 2010 15:12:17 +0100 blanchet make "debug" imply "blocking", since in blocking mode the exceptions flow through and are more instructive
Wed, 15 Dec 2010 18:10:32 +0100 blanchet facilitate debugging
Wed, 15 Dec 2010 17:14:44 +0100 blanchet clean up fudge factors a little bit
Wed, 15 Dec 2010 16:42:07 +0100 blanchet added weights to SMT problems
Wed, 15 Dec 2010 12:08:41 +0100 blanchet honor "overlord" option for SMT solvers as well and don't pass "ext" to them
Wed, 15 Dec 2010 11:26:29 +0100 blanchet crank up Metis's timeout for SMT solvers, since users love Metis
Wed, 15 Dec 2010 11:26:29 +0100 blanchet generate a "using [[smt_solver = ...]]" command if a proof is found by another SMT solver than the current one, to ensure it's also used for reconstruction
Wed, 15 Dec 2010 11:26:28 +0100 blanchet added Sledgehammer support for higher-order propositional reasoning
Wed, 15 Dec 2010 11:26:28 +0100 blanchet implemented partially-typed "tags" type encoding
Wed, 15 Dec 2010 11:26:28 +0100 blanchet implemented new type system encoding "overload_args", which is more lightweight than "const_args" (the unsound default) and hopefully almost as sound
Wed, 15 Dec 2010 11:26:28 +0100 blanchet added "type_sys" option to Sledgehammer
Wed, 15 Dec 2010 08:39:24 +0100 boehmes re-ordered SMT normalization code (eta-normalization, lambda abstractions and partial functions will be dealt with on the term level);
Fri, 10 Dec 2010 09:18:17 +0100 krauss made smlnj happy
Wed, 08 Dec 2010 22:18:37 +0100 blanchet lower fudge factor
Wed, 08 Dec 2010 22:17:53 +0100 blanchet implicitly call the minimizer for SMT solvers that don't return an unsat core
Wed, 08 Dec 2010 22:17:52 +0100 blanchet renamings
Wed, 08 Dec 2010 22:17:52 +0100 blanchet moved function to later module

Wed, 08 Dec 2010 22:17:52 +0100 blanchet split "Sledgehammer" module into two parts, to resolve forthcoming dependency problems
