Proof step 3 from proof maxpath-array-ls (conclusion)

⊦ is_array(str, r, st) ∧ st[r -- i '] = refval(r0) ∧ 0 ≤ i ∧ i < st[r -- _length] .intval ∧ ¬ junkref(str, r, st) ∧ ¬ cyclic(str, r, st) → ¬ maxpath(str, r, st) < maxpath(str, r0, st)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 2:
st[r -- i '] = refval(r0), 0 < st[r -- _length] .intval, 0 ≤ i, i < st[r -- _length] .intval, is_array(str, r, st), maxpath(str, r, st) < maxpath(str, r0, st) ⊦ junkref(str, r, st), cyclic(str, r, st)
