Proof step 5 from proof tr-fold-t (conclusion)

⊦ (r => mknode(r0, a, r1) * tr(r0, t0) * tr(r1, t1) * P0 * P1)(H) → (¬ (tr(r, branch(t0, a, t1)) * P0 * true)(H) ↔ false)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 4:
(r => mknode(r0, a, r1) * tr(r0, t0) * tr(r1, t1) * P0 * P1)(H) ⊦ (tr(r, branch(t0, a, t1)) * P0 * true)(H)
