The weightgap principle applies (using the following constant
growth matrix-interpretation)
The following argument positions are usable:
Uargs(c_2) = {1}, Uargs(c_3) = {1, 2}, Uargs(c_4) = {1},
Uargs(c_5) = {1, 2}, Uargs(c_6) = {1}, Uargs(c_7) = {1, 2},
Uargs(c_8) = {1}, Uargs(c_9) = {1, 2}, Uargs(c_10) = {1},
Uargs(c_11) = {1, 2}, Uargs(c_12) = {1}, Uargs(c_13) = {1, 2},
Uargs(c_14) = {1}, Uargs(c_15) = {1, 2}, Uargs(c_16) = {1},
Uargs(c_17) = {1, 2}, Uargs(c_18) = {1}, Uargs(c_19) = {1, 2},
Uargs(c_20) = {1}, Uargs(c_21) = {1, 2}

We use the processor 'matrix interpretation of dimension 1' to
orient following rules strictly.

Sub-proof:
----------
The following argument positions are usable:
Uargs(c_19) = {2}
TcT has computed the following constructor-based matrix
interpretation satisfying not(EDA).
[s](x1) = [1] x1 + [3]
[f_9^#](x1) = [0]
[g_10^#](x1, x2) = [4] x1 + [3]
[c_19](x1, x2) = [1] x2 + [4]
The order satisfies the following ordering constraints:
[g_10^#(s(x), y)] = [4] x + [15]
> [4] x + [7]
= [c_19(f_9^#(y), g_10^#(x, y))]
The strictly oriented rules are moved into the weak component.

We use the processor 'matrix interpretation of dimension 1' to
orient following rules strictly.
DPs:
{ 2: g_8^#(s(x), y) -> c_16(f_7^#(y), g_8^#(x, y))
, 3: f_9^#(x) -> g_9^#(x, x) }
Sub-proof:
----------
The following argument positions are usable:
Uargs(c_15) = {1}, Uargs(c_16) = {2}
TcT has computed the following constructor-based matrix
interpretation satisfying not(EDA).
[s](x1) = [1] x1 + [4]
[f_7^#](x1) = [1]
[f_8^#](x1) = [4] x1 + [0]
[g_8^#](x1, x2) = [2] x1 + [0]
[f_9^#](x1) = [7] x1 + [1]
[g_9^#](x1, x2) = [5] x2 + [0]
[g_10^#](x1, x2) = [7] x2 + [1]
[c_15](x1) = [2] x1 + [0]
[c_16](x1, x2) = [3] x1 + [1] x2 + [4]
The order satisfies the following ordering constraints:
[f_8^#(x)] = [4] x + [0]
>= [4] x + [0]
= [c_15(g_8^#(x, x))]
[g_8^#(s(x), y)] = [2] x + [8]
> [2] x + [7]
= [c_16(f_7^#(y), g_8^#(x, y))]
[f_9^#(x)] = [7] x + [1]
> [5] x + [0]
= [g_9^#(x, x)]
[g_9^#(s(x), y)] = [5] y + [0]

[g_9^#(s(x), y)] = [5] y + [0]

[g_10^#(s(x), y)] = [7] y + [1]
>= [7] y + [1]
= [f_9^#(y)]
[g_10^#(s(x), y)] = [7] y + [1]
>= [7] y + [1]
= [g_10^#(x, y)]
The strictly oriented rules are moved into the weak component.
We are left with following problem, upon which TcT provides the

TcT has computed the following constructor-restricted matrix
interpretation. Note that the diagonal of the component-wise maxima
of interpretation-entries (of constructors) contains no more than 0
non-zero entries.
[s](x1) = [1]
[f_7^#](x1) = [0]
[f_8^#](x1) = [1]
[g_8^#](x1, x2) = [0]

[g_10^#](x1, x2) = [6]
[c_15](x1) = [0]

[c_4](x1) = [1] x1 + [0]
[c_5](x1) = [1] x1 + [0]

The order satisfies the following ordering constraints:

The following argument positions are usable:

TcT has computed the following constructor-restricted matrix
interpretation. Note that the diagonal of the component-wise maxima
of interpretation-entries (of constructors) contains no more than 0

orient following rules strictly.
