The weightgap principle applies (using the following constant
growth matrix-interpretation)
The following argument positions are usable:
Uargs(c_3) = {1, 2}, Uargs(c_4) = {1, 2}, Uargs(c_5) = {1, 2}
TcT has computed the following constructor-restricted matrix
interpretation.
[t] = [0]
[0]
[constant] = [0]
[0]
[+](x1, x2) = [1 0] x1 + [1 0] x2 + [0]
[0 0] [0 0] [0]
[*](x1, x2) = [1 0] x1 + [1 0] x2 + [0]
[0 0] [0 0] [0]
[-](x1, x2) = [1 0] x1 + [1 0] x2 + [0]
[0 0] [0 0] [0]
[D^#](x1) = [1]
[0]
[c_1] = [0]
[0]
[c_2] = [0]
[0]
[c_3](x1, x2) = [1 0] x1 + [1 0] x2 + [2]
[0 1] [0 1] [0]
[c_4](x1, x2) = [1 0] x1 + [1 0] x2 + [2]
[0 1] [0 1] [0]
[c_5](x1, x2) = [1 0] x1 + [1 0] x2 + [2]
[0 1] [0 1] [0]
The order satisfies the following ordering constraints:
[D^#(t())] = [1]
[0]
> [0]
[0]
= [c_1()]
[D^#(constant())] = [1]
[0]
> [0]
[0]
= [c_2()]
[D^#(+(x, y))] = [1]
[0]
? [4]
[0]
= [c_3(D^#(x), D^#(y))]
[D^#(*(x, y))] = [1]
[0]
? [4]
[0]
= [c_4(D^#(x), D^#(y))]
[D^#(-(x, y))] = [1]
[0]
? [4]
[0]
= [c_5(D^#(x), D^#(y))]
Further, it can be verified that all rules not oriented are covered by the weightgap condition.

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

The following argument positions are usable:
Uargs(c_3) = {1, 2}, Uargs(c_4) = {1, 2}, Uargs(c_5) = {1, 2}
TcT has computed the following constructor-based matrix
interpretation satisfying not(EDA).
[+](x1, x2) = [1] x1 + [1] x2 + [2]
[*](x1, x2) = [1] x1 + [1] x2 + [0]

[c_3](x1, x2) = [1] x1 + [1] x2 + [1]
[c_4](x1, x2) = [1] x1 + [1] x2 + [0]
[c_5](x1, x2) = [1] x1 + [1] x2 + [0]
The order satisfies the following ordering constraints:
[D^#(+(x, y))] = [4] x + [4] y + [8]
> [4] x + [4] y + [1]
= [c_3(D^#(x), D^#(y))]
[D^#(*(x, y))] = [4] x + [4] y + [0]
>= [4] x + [4] y + [0]

[D^#(-(x, y))] = [4] x + [4] y + [8]
