Proof step 20 from proof nodes-cons-rec (previous step)

# ax = # ndx, (@(m, m0, m1) ' + ax)[n] = @(m3, m4, m5), gstore[@(m, m0, m1)] = mkgnode(nd, m2, boolvar, boolvar0), @(m, m0, m1) ∈ gstore, n ≤ # ndx, ∀ n. n < # ndx → ax[n] ∈ gstore ∧ ¬ ax[n].lnum ∈ ginval ∧ gstore[ax[n]].nd = ndx[n] ⊦ m ∈ ginval, @(m3, m4, m5) ∈ gstore ∧ ¬ m3 ∈ ginval ∧ gstore[@(m3, m4, m5)].nd = (nd ' + ndx)[n]

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 21:
# ax = # ndx, gstore[@(m, m0, m1)] = mkgnode(nd, m2, boolvar, boolvar0), (@(m, m0, m1) ' + ax)[n] = @(m3, m4, m5), gstore[@(m3, m4, m5)] = mkgnode(nd0, m6, boolvar1, boolvar2), @(m, m0, m1) ∈ gstore, n ≤ # ndx, ∀ n. n < # ndx → ax[n] ∈ gstore ∧ ¬ ax[n].lnum ∈ ginval ∧ gstore[ax[n]].nd = ndx[n] ⊦ m ∈ ginval, @(m3, m4, m5) ∈ gstore ∧ ¬ m3 ∈ ginval ∧ nd0 = (nd ' + ndx)[n]

Rule argument

spec: groupnode name: elim seq: ⊦ ((nd = gnd.nd ∧ m = gnd.sqnum) ∧ (boolvar ↔ gnd.start)) ∧ (boolvar0 ↔ gnd.end) ↔ gnd = mkgnode(nd, m, boolvar, boolvar0) subst: [gnd, nd, m, boolvar, boolvar0] → [gstore[@(m3, m4, m5)], nd0, m6, boolvar1, boolvar2]

Additional information

Used simplifier rules: ⊦ ((nd = gnd.nd ∧ m = gnd.sqnum) ∧ (boolvar ↔ gnd.start)) ∧ (boolvar0 ↔ gnd.end) ↔ gnd = mkgnode(nd, m, boolvar, boolvar0); (elim) Used terms: gstore[@(m3, m4, m5)], nd0, m6, boolvar1, boolvar2
