Proof step 11 from proof min-concat (previous step)

∀ x0, y0. # x0 + # y0 < # (i + []) + # (i0 + x2) → (true → x0 = [] ∨ y0 = [] ∨ min(x0 + y0) = min(min(x0), min(y0))) ⊦ min(min(i, i0), min(max(i, i0) ' + x2)) = min(min(i0 ' + x2), i)

User applied rule apply induction

And obtained the following new goals

Proof step 10:
max(i, i0) ' = [] ∨ x2 = [] ∨ min(max(i, i0) ' + x2) = min(min(max(i, i0) '), min(x2)), ∀ x0, y0. # x0 + # y0 < # (i + []) + # (i0 + x2) → (true → x0 = [] ∨ y0 = [] ∨ min(x0 + y0) = min(min(x0), min(y0))) ⊦ min(min(i, i0), min(max(i, i0) ' + x2)) = min(min(i0 ' + x2), i)

Rule argument

[substlist-arg: [x0, y0] → [max(i, i0) ', x2]]
