and S is the following TRS.

0(1(2(3(4(5(x1)))))) 0(1(2(3(4(5(x1)))))) (97)

Property / Task

Prove or disprove termination.

Answer / Result

Yes.

Proof (by matchbox @ termCOMP 2023)

1 Closure Under Flat Contexts

Using the flat contexts

{5(), 4(), 3(), 2(), 1(), 0()}

We obtain the transformed TRS

There are 576 ruless (increase limit for explicit display).

1.1 Semantic Labeling

The following interpretations form a model of the rules.

As carrier we take the set {0,...,5}. Symbols are labeled by the interpretation of their arguments using the interpretations (modulo 6):

[5(x1)] = 6x1 + 0
[4(x1)] = 6x1 + 1
[3(x1)] = 6x1 + 2
[2(x1)] = 6x1 + 3
[1(x1)] = 6x1 + 4
[0(x1)] = 6x1 + 5

We obtain the labeled TRS

There are 3456 ruless (increase limit for explicit display).

1.1.1 Rule Removal

Using the matrix interpretations of dimension 1 with strict dimension 1 over the rationals with delta = 1
[50(x1)] = x1 +
1
[51(x1)] = x1 +
0
[52(x1)] = x1 +
7
[53(x1)] = x1 +
6
[54(x1)] = x1 +
0
[55(x1)] = x1 +
0
[40(x1)] = x1 +
0
[41(x1)] = x1 +
6
[42(x1)] = x1 +
6
[43(x1)] = x1 +
6
[44(x1)] = x1 +
0
[45(x1)] = x1 +

[30(x1)] = x1 +

[31(x1)] = x1 +
6
[32(x1)] = x1 +
7
[33(x1)] = x1 +
7
[34(x1)] = x1 +

[35(x1)] = x1 +
0
[20(x1)] = x1 +
7
[21(x1)] = x1 +
6
[22(x1)] = x1 +
6
[23(x1)] = x1 +
7
[24(x1)] = x1 +

[25(x1)] = x1 +

[10(x1)] = x1 +

[11(x1)] = x1 +

[02(x1)] = x1 +
1
[03(x1)] = x1 +

[04(x1)] = x1 +
0
[05(x1)] = x1 +
0
all of the following rules can be deleted.

There are 3456 ruless (increase limit for explicit display).

1.1.1.1 R is empty

There are no rules in the TRS. Hence, it is terminating.
