2014-03-03 blanchet 2014-03-03 tuned code
2011-11-07 blanchet 2011-11-07 avoid infinite recursion in peephole optimizer function -- this had a debilitating effect on rationals and reals
2010-08-01 blanchet 2010-08-01 added manual symmetry breaking for datatypes
2010-04-25 blanchet 2010-04-25 remove "show_skolems" option and change style of record declarations
2010-04-24 blanchet 2010-04-24 remove type annotations as comments; Nitpick is now 1136 lines shorter
2010-02-25 blanchet 2010-02-25 improved precision of infinite "shallow" datatypes in Nitpick; e.g. strings used for variable names, instead of an opaque type
2010-02-22 blanchet 2010-02-22 enabled Nitpick's support for quotient types + shortened the Nitpick tests a bit
2010-02-22 blanchet 2010-02-22 fixed a few bugs in Nitpick and removed unreferenced variables
2010-02-02 blanchet 2010-02-02 added support for nonstandard models to Nitpick (based on an idea by Koen Claessen) and did other fixes to Nitpick
2010-01-20 blanchet 2010-01-20 some work on Nitpick's support for quotient types; quotient types are not yet in Isabelle, so for now I hardcoded "IntEx.my_int"
2009-12-18 blanchet 2009-12-18 polished Nitpick's binary integer support etc.; etc. = improve inconsistent scope correction + sort values nicely in output + handle "mod" using the characterization "x mod y = x - x div y * y" (instead of explicit code in Nitpick) + introduce KK = Kodkod as abbreviation
2009-12-17 blanchet 2009-12-17 added support for binary nat/int representation to Nitpick
2009-12-04 blanchet 2009-12-04 fixed paths in Nitpick's ML file headers
2009-11-13 blanchet 2009-11-13 removed a few global names in Nitpick (styp, nat_less, pairf)
2009-10-27 blanchet 2009-10-27 internal renaming in Nitpick and fixed Kodkodi invokation on Linux; renamed Nitpick's ML structures from NitpickXxx to Nitpick_Xxx and added KODKODI_JAVA_LIBRARY_PATH to LD_LIBRARY_PATH before invoking Kodkodi
2009-10-22 blanchet 2009-10-22 added Nitpick's theory and ML files to Isabelle/HOL; the examples and the documentation are on their way.
