Proof step 4 from proof CRely-refl (previous step)

¬(CGuar(m +1, act, cs, act, cs) ∧ m ≠ m +1 ∧ CInv(n, act, cs) ∧ CInv(n, act, cs)), CInv(n, act, cs) ⊦ CRely(m, act, cs, act, cs)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 5:
CInv(n, act, cs) ⊦ CRely(m, act, cs, act, cs), CGuar(m + 1, act, cs, act, cs)

Rule argument
