Proof step 1 from proof prepost-create-gcheap (conclusion)

lpt0 = lpt ⊦ ⟪persistence_create_gcheap#(nx; lpt, gch)⟫ (bin-heap-inv(gch, lpt) ∧ gc-heap(lpt, nx) = keyset(gch) ∧ id-idx(lpt0, lpt))

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 2:
lpt0 = lpt ⊦ ⟪persistence_create_gcheap#(nx; lpt, gch)⟫ (bin-heap-inv(gch, lpt) ∧ gc-heap(lpt0, nx) = keyset(gch) ∧ id-idx(lpt0, lpt))

Rule argument

Additional information

Used simplifier rules: ⊦ id-idx(lpt0, lpt1) → gc-heap(lpt1, nx) = gc-heap(lpt0, nx); (s)
