properly unmangle names in path finder

only uncombine combinators in textual Isar proofs, not in Metis

properly locate helpers whose constants have several entries in the helper table

skip "hBOOL" in new Metis path finder

don't pass "~ " to new Metis

tuning

gracefully handle the case where a constant is partially or not instantiated at all, as may happen when reconstructing Metis proofs for polymorphic type encodings

temporarily document "metisX"

use "metisX" as fallback, since it's much faster than "metisFT"

temporarily added "MetisX" as reconstructor and minimizer

ensured that the logic for "explicit_apply = smart" also works on CNF (i.e. new Metis)

show what failed to play

refined auto minimization code: don't use Metis if Isar proofs are desired, and fall back on prover if Metis is too slow

tuning

killed odd connectives

added Metis examples to test the new type encodings

tuned CASC method

clean up unnecessary machinery -- helpers work also with monomorphic type encodings

added support for helpers in new Metis, so far only for polymorphic type encodings

imported rest of new IMP

atLeastAtMostSuc_conv on int

fixed typo

updated SMT certificates

made introduction of explicit application stable under removal of vacuous facts (which only lower the rank of constants but do not participate in the proof)

changing the mira setting again for the mutabelle configuration

adding more settings to mira's mutabelle configuration

merged

Added typed IMP
