Proof step 156 from proof kappa-RED1 (previous step)

〈tn5 := some(tn5 .t _ (t0 _ t1) .2)〉 tn5 = tn0, 〈RED1((t0 _ t1) .1; tn4)〉 tn4 = tn5, 〈TOPRED(t0 _ t1; tn)〉 tn = tn4, 〈RED1(t0; tn3): m 〉 tn3 = none, 〈TOPRED(t0 _ t1; tn2): m 〉 tn2 = none, ∀ n0, t, tn1, tn0. n0 < m + 1 → (〈RED1(t; tn2): n0 〉 tn2 = tn1 ∧ 〈RED1(t; tn2)〉 tn2 = tn0 ∧ tn0 ≠ tn1 → false), tn0 ≠ none, ¬ value(t0), tn4 = none, tn5 ≠ none ⊦

Heuristic symbolic execution applied rule assign left

And obtained the following new goals

Proof step 155:
〈RED1((t0 _ t1) .1; tn4)〉 tn4 = tn5, 〈TOPRED(t0 _ t1; tn)〉 tn = tn4, 〈RED1(t0; tn3): m 〉 tn3 = none, 〈TOPRED(t0 _ t1; tn2): m 〉 tn2 = none, ∀ n0, t, tn1, tn0. n0 < m + 1 → (〈RED1(t; tn2): n0 〉 tn2 = tn1 ∧ 〈RED1(t; tn2)〉 tn2 = tn0 ∧ tn0 ≠ tn1 → false), tn0 ≠ none, ¬ value(t0), tn4 = none, tn5 ≠ none, some(tn5 .t _ (t0 _ t1) .2) = tn0 ⊦
