blanchet [Thu, 14 Apr 2011 11:24:05 +0200] rev 42347
properly implemented definitional CNF for the new Skolemizer (and moved the code for the old Skolemizer -- tuning), removing big chunks for experimental/debugging code
blanchet [Thu, 14 Apr 2011 11:24:05 +0200] rev 42346
remove experimental code added in 85bb6fbb8e6a
blanchet [Thu, 14 Apr 2011 11:24:05 +0200] rev 42345
added examples of definitional CNF facts
blanchet [Thu, 14 Apr 2011 11:24:05 +0200] rev 42344
"unify_first_prem_with_concl" (cf. 9ceb585c097a) sometimes throws an exception, but it is very rarely needed -- catch the exception for now
blanchet [Thu, 14 Apr 2011 11:24:05 +0200] rev 42343
compile
blanchet [Thu, 14 Apr 2011 11:24:05 +0200] rev 42342
handle case where the same Skolem name is given different types in different subgoals in the new Skolemizer (this can happen if several type-instances of the same fact are needed by Metis, cf. example in "Clausify.thy") -- the solution reintroduces old code removed in a6725f293377
blanchet [Thu, 14 Apr 2011 11:24:04 +0200] rev 42341
removed obsolete Skolem counter in new Skolemizer
blanchet [Thu, 14 Apr 2011 11:24:04 +0200] rev 42340
added outstanding issue to Metis example
blanchet [Thu, 14 Apr 2011 11:24:04 +0200] rev 42339
use the list of actually used axioms to (correctly) precompute the "outer params", not all axioms
blanchet [Thu, 14 Apr 2011 11:24:04 +0200] rev 42338
started clausifier examples
blanchet [Thu, 14 Apr 2011 11:24:04 +0200] rev 42337
make new Skolemizer work also for "metisFT"
blanchet [Thu, 14 Apr 2011 11:24:04 +0200] rev 42336
improve definitional CNF on goal by moving "not" past the quantifiers
blanchet [Thu, 14 Apr 2011 11:24:04 +0200] rev 42335
experiment with definitional CNF
blanchet [Thu, 14 Apr 2011 11:24:04 +0200] rev 42334
use old Skolemizer for Metis call that requires high unification bound (around 100) with the new Skolemizer
blanchet [Thu, 14 Apr 2011 11:24:04 +0200] rev 42333
try to repair out-of-sync situations in Metis
blanchet [Thu, 14 Apr 2011 11:24:04 +0200] rev 42332
handle Vampire [predicate definition introduction] steps the same way as missing proof, since such steps do not report which axioms were used
noschinl [Wed, 13 Apr 2011 21:38:00 +0200] rev 42331
Add YXML.parse_file to signature ...
noschinl [Wed, 13 Apr 2011 21:23:30 +0200] rev 42330
Add YXML.parse_file to parse and process big data files

more permissive run_command: identity execution for empty toplevel, e.g. after malformed theory header;
wenzelm [Mon, 11 Apr 2011 17:11:03 +0200] rev 42327
Name_Space.entry_markup: keep def position as separate properties;
uniform treatment of ML_def/ML_open/ML_struct as entities;
hyperlinks for all entities -- excluding ML_open/ML_struct for now;
wenzelm [Sat, 09 Apr 2011 23:29:50 +0200] rev 42326
some position reports for 'translations';
wenzelm [Sat, 09 Apr 2011 15:00:23 +0200] rev 42325

wenzelm [Sat, 09 Apr 2011 13:10:20 +0200] rev 42324
merged
boehmes [Fri, 08 Apr 2011 19:04:08 +0200] rev 42323
added SMT certificates
boehmes [Fri, 08 Apr 2011 19:04:08 +0200] rev 42322
use unification instead of matching to find proper assertions (which might not match original assumptions due to lambda-lifting and introduction of fresh variables)
boehmes [Fri, 08 Apr 2011 19:04:08 +0200] rev 42321
fixed eta-expansion: use correct order to apply new bound variables
boehmes [Fri, 08 Apr 2011 19:04:08 +0200] rev 42320
check if negating the goal is possible (avoids CTERM exception for Pure propositions)
boehmes [Fri, 08 Apr 2011 19:04:08 +0200] rev 42319
unfold and eta-contract let expressions before lambda-lifting to avoid bad terms
boehmes [Fri, 08 Apr 2011 19:04:08 +0200] rev 42318
corrected order of steps in Z3 proof reconstruction for elimination of unused quantified variables: first try to eliminate unused variables, then skip over used variables
