Proof step 15 from proof kappa-TOPRED (previous step)

〈if value(v4) ∧ value(v0) ∧ value(v) then tn := some(v4 _ v _ (v0 _ v)) else tn := none〉 tn = tn0, tn0 ≠ some(t4 _ t1 _ (t3 _ t1)), n ≠ 0, value(t4), value(t3), value(t1), v = (S _ t4 _ t3 _ t1) .2, v0 = (S _ t4 _ t3 _ t1) .1 .2, v4 = (S _ t4 _ t3 _ t1) .1 .1 .2 ⊦

Heuristic symbolic execution applied rule if positive left

And obtained the following new goals

Proof step 14:
〈tn := some(v4 _ v _ (v0 _ v))〉 tn = tn0, tn0 ≠ some(t4 _ t1 _ (t3 _ t1)), n ≠ 0, value(t4), value(t3), value(t1), v = (S _ t4 _ t3 _ t1) .2, v0 = (S _ t4 _ t3 _ t1) .1 .2, v4 = (S _ t4 _ t3 _ t1) .1 .1 .2 ⊦
