and#(not(not(x)),y,not(z)) -> c_1(and#(y,band(x,z),x))
Weak DPs
and mark the set of starting terms.

+ Considered Problem:

WeightGap {wgDimension = 1, wgDegree = 0, wgKind = Algebraic, wgUArgs = UArgs, wgOn = WgOnAny}
+ Details:
The weightgap principle applies using the following constant growth matrix-interpretation:
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_1) = {1}
Following symbols are considered usable:
all
TcT has computed the following interpretation:
p(and) = [4] x1 + [2] x2 + [1] x3 + [4]
p(band) = [0]
p(not) = [1]
p(and#) = [1] x1 + [2] x2 + [0]
p(c_1) = [1] x1 + [0]
Following rules are strictly oriented:
and#(not(not(x)),y,not(z)) = [2] y + [1]
> [1] y + [0]
= c_1(and#(y,band(x,z),x))
Following rules are (at-least) weakly oriented:
Further, it can be verified that all rules not oriented are covered by the weightgap condition.
