We add the following weak dependency pairs:
Strict DPs:
{ *^#(x, +(y, z)) -> c_1(*^#(x, y), *^#(x, z))
, *^#(x, 1()) -> c_2()
, *^#(+(x, y), z) -> c_3(*^#(x, z), *^#(y, z))
, *^#(1(), y) -> c_4() }
and mark the set of starting terms.

No rule is usable, rules are removed from the input problem.

Answer:
YES(O(1),O(n^2))
The weightgap principle applies (using the following constant
growth matrix-interpretation)
The following argument positions are usable:
Uargs(c_1) = {1, 2}, Uargs(c_3) = {1, 2}
TcT has computed the following constructor-restricted matrix
interpretation.
[+](x1, x2) = [1 0] x1 + [1 0] x2 + [0]
[0 0] [0 0] [0]
[1] = [0]
[0]
[*^#](x1, x2) = [2]
[0]
[c_1](x1, x2) = [1 0] x1 + [1 0] x2 + [2]
[0 1] [0 1] [2]
[c_2] = [0]
[0]
[c_3](x1, x2) = [1 0] x1 + [1 0] x2 + [2]
[0 1] [0 1] [2]
[c_4] = [0]
[0]
The order satisfies the following ordering constraints:
[*^#(x, +(y, z))] = [2]
[0]
? [6]
[2]
= [c_1(*^#(x, y), *^#(x, z))]
[*^#(x, 1())] = [2]
[0]
> [0]
[0]
= [c_2()]
[*^#(+(x, y), z)] = [2]
[0]
? [6]
[2]
= [c_3(*^#(x, z), *^#(y, z))]
[*^#(1(), y)] = [2]
[0]
> [0]
[0]
= [c_4()]
Further, it can be verified that all rules not oriented are covered by the weightgap condition.

The following weak DPs constitute a sub-graph of the DG that is
closed under successors. The DPs are removed.

Answer:
YES(O(1),O(n^2))
We use the processor 'custom shape polynomial interpretation' to
orient following rules strictly.
DPs:
{ 1: *^#(x, +(y, z)) -> c_1(*^#(x, y), *^#(x, z))
, 2: *^#(+(x, y), z) -> c_3(*^#(x, z), *^#(y, z)) }
Sub-proof:
----------
The following argument positions are considered usable:
Uargs(c_1) = {1, 2}, Uargs(c_3) = {1, 2}
TcT has computed the following constructor-restricted polynomial
interpretation.
[+](x1, x2) = 2 + x1 + x2
[*^#](x1, x2) = 1 + 2*x1 + 2*x1*x2 + x2
[c_1](x1, x2) = x1 + x2
[c_3](x1, x2) = 2 + x1 + x2
This order satisfies the following ordering constraints.
[*^#(x, +(y, z))] = 3 + 6*x + 2*x*y + 2*x*z + y + z
> 2 + 4*x + 2*x*y + y + 2*x*z + z
= [c_1(*^#(x, y), *^#(x, z))]
[*^#(+(x, y), z)] = 5 + 2*x + 2*y + 5*z + 2*x*z + 2*y*z
> 4 + 2*x + 2*x*z + 2*z + 2*y + 2*y*z
= [c_3(*^#(x, z), *^#(y, z))]
The strictly oriented rules are moved into the weak component.
We are left with following problem, upon which TcT provides the
certificate YES(O(1),O(1)).
