blanchet [Wed, 15 Dec 2010 11:26:28 +0100] rev 41143
remove at most one double negation -- any other double negations are part of some higher-order reasoning and should be left alone, cf. "HO_Reas.thy"
blanchet [Wed, 15 Dec 2010 11:26:28 +0100] rev 41142
weaken the "expect" flag so that it doesn't trigger errors if a prover is not installed
blanchet [Wed, 15 Dec 2010 11:26:28 +0100] rev 41141
added example to exercise higher-order reasoning with Sledgehammer and Metis
blanchet [Wed, 15 Dec 2010 11:26:28 +0100] rev 41140
added Sledgehammer support for higher-order propositional reasoning
blanchet [Wed, 15 Dec 2010 11:26:28 +0100] rev 41139
add Metis support for higher-order propositional reasoning
blanchet [Wed, 15 Dec 2010 11:26:28 +0100] rev 41138
implemented partially-typed "tags" type encoding
blanchet [Wed, 15 Dec 2010 11:26:28 +0100] rev 41137
implemented "no_types" encoding, which is too unsound to be useful but can come in handy for evaluations
blanchet [Wed, 15 Dec 2010 11:26:28 +0100] rev 41136
implemented new type system encoding "overload_args", which is more lightweight than "const_args" (the unsound default) and hopefully almost as sound
