Due to missing edges in the depndency graph, the right-hand sides of following rules could be simplified:
c#(a(a(0(),x),y)) -> c_2(c#(c(c(0()))),c#(c(0())))

NaturalMI {miDimension = 1, miDegree = 0, miKind = Algebraic, uargs = UArgs, urules = URules, selector = Just any strict-rules, greedy = NoGreedy}
Proof:
We apply a matrix interpretation of kind constructor based matrix interpretation (containing no more than 0 non-zero interpretation-entries in the diagonal of the component-wise maxima):
The following argument positions are considered usable:
uargs(c_2) = {1,2}
Following symbols are considered usable:
{c,c#}
TcT has computed the following interpretation:
p(0) = [0]
p(a) = [12]
p(c) = [2] x1 + [1]
p(c#) = [2] x1 + [6]
p(c_1) = [0]
p(c_2) = [1] x1 + [1] x2 + [4]
Following rules are strictly oriented:
c#(a(a(0(),x),y)) = [30]
> [24]
= c_2(c#(c(c(0()))),c#(c(0())))
Following rules are (at-least) weakly oriented:
c(y) = [2] y + [1]
>= [1] y + [0]
= y
c(a(a(0(),x),y)) = [25]
>= [12]
= a(c(c(c(0()))),y)
