To remove rules and DPs from this DP problem we used the following monotonic and CE-compatible order: Polynomial ordering.
Polynomial interpretation:
POL(#) | = 0 |
POL(-'(x1, x2)) | = 1 + x1 + x2 |
POL(0(x1)) | = x1 |
POL(1(x1)) | = x1 |
POL(-(x1, x2)) | = x1 + x2 |
We have the following set D of usable symbols: {#, -', 0, 1, -}
No Dependency Pairs can be deleted.
54 non usable rules have been deleted.
The result of this processor delivers one new DP problem.

The following Dependency Pairs can be deleted as the lhs is strictly greater than the corresponding rhs:
-'(1(x), 1(y)) -> -'(x, y)
-'(1(x), 0(y)) -> -'(x, y)
-'(0(x), 1(y)) -> -'(x, y)

-'(0(x), 0(y)) -> -'(x, y)
No Rules can be deleted.
After the removal, there are no SCCs in the dependency graph which results in no DP problems which have to be solved.
