Input

The rewrite relation of the following TRS is considered.

The following set of initial dependency pairs has been identified.

The dependency pairs are split into 1 component.

The 1^st component contains the pairs

a^#(c(b(x0)))	→	a^#(a(x0))
a^#(c(b(x0)))	→	a^#(x0)

Using the linear polynomial interpretation over (2 x 2)-matrices with strict dimension 1 over the arctic semiring over the integers

[b(x₁)]

-∞	-∞
0	0

· x₁ +

0	-∞
2	-∞

[a^#(x₁)]

0	0
-∞	-∞

· x₁ +

0	-∞
-∞	-∞

[a(x₁)]

0	0
0	0

· x₁ +

0	-∞
2	-∞

[c(x₁)]

-∞	1
0	0

· x₁ +

1	-∞
2	-∞

together with the usable rules

(w.r.t. the implicit argument filter of the reduction pair), all pairs could be removed.

There are no pairs anymore.
