Proof step 230 from proof kappa-RED1 (previous step)

〈tn4 := some(tn4 .t _ (S _ t4 _ t3 _ t1) .2)〉 tn4 = tn0, 〈RED1((S _ t4 _ t3 _ t1) .1; tn2)〉 tn2 = tn4, 〈TOPRED(S _ t4 _ t3 _ t1; tn)〉 tn = tn2, ∀ n0, t, tn1, tn0. n0 < m + 1 → (〈RED1(t; tn3): n0 〉 tn3 = tn1 ∧ 〈RED1(t; tn3)〉 tn3 = tn0 ∧ tn0 ≠ tn1 → false), tn0 ≠ some(t4 _ t1 _ (t3 _ t1)), m ≠ 0, value(t4), value(t3), value(t1), tn2 = none ∧ ap(S _ t4 _ t3 _ t1), tn4 ≠ none ⊦

Heuristic symbolic execution applied rule assign left

And obtained the following new goals

Proof step 229:
〈RED1((S _ t4 _ t3 _ t1) .1; tn2)〉 tn2 = tn4, 〈TOPRED(S _ t4 _ t3 _ t1; tn)〉 tn = tn2, ∀ n0, t, tn1, tn0. n0 < m + 1 → (〈RED1(t; tn3): n0 〉 tn3 = tn1 ∧ 〈RED1(t; tn3)〉 tn3 = tn0 ∧ tn0 ≠ tn1 → false), tn0 ≠ some(t4 _ t1 _ (t3 _ t1)), m ≠ 0, value(t4), value(t3), value(t1), tn2 = none ∧ ap(S _ t4 _ t3 _ t1), tn4 ≠ none, some(tn4 .t _ (S _ t4 _ t3 _ t1) .2) = tn0 ⊦
