Proof step 2 from proof delta-write-same (previous step)

wlar[n].ec = wle.ec ⊦ sum-of-differences(ecs(wlar[n, wle]).max, ecs(wlar[n, wle])) = sum-of-differences(ecs(wlar).max, ecs(wlar))

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 3:
wlar[n].ec = m, wle = wl-entry(m, stat) ⊦ sum-of-differences(ecs(wlar[n, wle]).max, ecs(wlar[n, wle])) = sum-of-differences(ecs(wlar).max, ecs(wlar))

Rule argument

spec: wlentry name: elim-02 seq: ⊦ m = wle.ec ∧ stat = wle.status ↔ wle = wl-entry(m, stat) subst: [wle, m, stat] → [wle, m, stat]

Additional information

Used simplifier rules: ⊦ m = wle.ec ∧ stat = wle.status ↔ wle = wl-entry(m, stat); (elim) Used terms: wle, m, stat
