   R
     ↳Dependency Pair Analysis



R contains the following Dependency Pairs:

ODD(s(x)) -> NOT(odd(x))
ODD(s(x)) -> ODD(x)
+'(x, s(y)) -> +'(x, y)
+'(s(x), y) -> +'(x, y)

Furthermore, R contains two SCCs.

     ↳DPs
       →DP Problem 1
         ↳Argument Filtering and Ordering
       →DP Problem 2
         ↳AFS


Dependency Pair:

ODD(s(x)) -> ODD(x)


Rules:


not(true) -> false
not(false) -> true
odd(0) -> false
odd(s(x)) -> not(odd(x))
+(x, 0) -> x
+(x, s(y)) -> s(+(x, y))
+(s(x), y) -> s(+(x, y))





The following dependency pair can be strictly oriented:

ODD(s(x)) -> ODD(x)


There are no usable rules using the Ce-refinement that need to be oriented.
Used ordering: Homeomorphic Embedding Order with EMB
resulting in one new DP problem.
Used Argument Filtering System:
ODD(x1) -> ODD(x1)
s(x1) -> s(x1)
