Proof step 14 from proof to-vtbl-size (previous step)

∀ vols1. # vols1 < # vols0[v, ebatbl] → true → # to-vtbl(vols1) = # vols1 ⊦ # to-vtbl(vols0) = # vols0, v ∈ vols0

User applied rule apply induction

And closed the goal!

Rule argument

subst: [vols1] → [vols0]

Additional information

Used simplifier rules: ⊦ ¬ v ∈ vols → # vols[v, ebatbl] = # vols + 1; (s)% ⊦ m < n + 1 ↔ ¬ n < m; (s)% ⊦ ¬ n < n; (s)%a: ⊦ (m + n0) + n1 = m + n0 + n1; from specification nat-basic%c: ⊦ m + n = n + m; from specification nat-basic Used terms: vols0
