Proof step 4 from proof min-del-nlz (previous step)

ints ≠ [], min(ints -l i0) < 0, min(ints -l i0) < min(i, min(ints)), 0 < min(i, min(ints)) ⊦

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 5:
min(ints -l i0) < 0, min(ints -l i0) < min(i, min(ints)), 0 < min(i, min(ints)) ⊦ ints = []

Rule argument

Additional information

Used simplifier rules: transitivity: ⊦ i < i0 ∧ i0 < i1 → i < i1; (forward) from specification oelem[intlista]%forward-le-05: ⊦ i < j ∧ 0 ≤ i → 0 < j; (forward) from specification int-abs
