Proof step 2 from proof size-copy (previous step)

∀ ar, m, ar0, m0. # copy(ar, m, ar0, m0, n0) = # ar0 ⊦ # copy(ar, m, ar0, m0, n0 +1) = # ar0

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 3:
∀ ar, m, ar0, m0. # copy(ar, m, ar0, m0, n0) = # ar0 ⊦ # copy(ar, m, ar0, m0, n0) = # ar0

Rule argument

Used simplifier rules: Copy-succ: ⊦ copy(ar, m, ar0, m0, n + 1) = copy(ar, m, ar0, m0, n)[m0 + n, ar[m + n]];%Size-put: ⊦ # ar[n, a] = # ar; from specification array%c: ⊦ m + n = n + m; from specification nat-basic2%a: ⊦ (m + n0) + n1 = m + n0 + n1; from specification nat-basic2%succ: ⊦ m +1 = m + 1; from specification nat-basic2
