Proof step 4 from proof unchanged-unchNorec-same (conclusion)

⊦ ¬ unchangedNorec(r, st, st0) ∧ is_obj(str, r, st) → ¬ unchanged(str, r, st, st0)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 3:
is_obj(str, r, st), unchanged(str, r, st, st0) ⊦ unchangedNorec(r, st, st0)
