Proof step 2 from proof prepost-next2pot (previous step)

2exp-size(n) ⊦ ⟪bin_min_heap_next_2pot(minsize; n)⟫ (2exp-size(n) ∧ minsize ≤ n)

Heuristic nonrecursive calls applied rule call right

And obtained the following new goals

Proof step 3:
2exp-size(n) ⊦ ⟪while n < minsize do n := n * 2⟫ (2exp-size(n) ∧ minsize ≤ n)

Rule argument

pos: right 1

Additional information

Used simplifier rules: bin_min_heap_next_2pot(minsize; n){while n < minsize do n := n * 2};
