src/solvers/qbf/qbf_bdd_core.cpp

 {
-  assert(false);
+  UNREACHABLE;
  return tvt(false);


Why is this required here and not below, eg in m_get?

    {
+      INVARIANT(
+        it->type == quantifiert::UNIVERSAL,
+        "Only handles quantified variables.");


start with lower case (several occurrences)

xbauch · 2018-09-18T14:44:24Z

Lower cases and full stops fixed, redundant return statements removed.

-    assert(model_bdds[l.var_no()]!=NULL);

While at it: please use nullptr instead of NULL

Remove the negation, i.e., the invariant is result, not !result

Added blank lines before util/invariant.h includes, fixed the skizzo invariant condition typo.
