Dependency Pair Analysis



R contains the following Dependency Pairs:

AG(X) -> AH(X)
AH(d) -> AG(c)
MARK(g(X)) -> AG(X)
MARK(h(X)) -> AH(X)
MARK(c) -> AC

Furthermore, R contains one SCC.

Polynomial Ordering


Dependency Pairs:

AH(d) -> AG(c)
AG(X) -> AH(X)


Rules:


ag(X) -> ah(X)
ag(X) -> g(X)
ac -> d
ac -> c
ah(d) -> ag(c)
ah(X) -> h(X)
mark(g(X)) -> ag(X)
mark(h(X)) -> ah(X)
mark(c) -> ac
mark(d) -> d


Strategy:

innermost




The following dependency pair can be strictly oriented:

AH(d) -> AG(c)


There are no usable rules for innermost that need to be oriented.

Used ordering: Polynomial ordering with Polynomial interpretation:
  POL(A__G(x1))=  x1  
  POL(c)=  0  
  POL(d)=  1  
  POL(A__H(x1))=  x1  

resulting in one new DP problem.

Dependency Graph


Dependency Pair:

AG(X) -> AH(X)


Rules:


ag(X) -> ah(X)
ag(X) -> g(X)
ac -> d
ac -> c
ah(d) -> ag(c)
ah(X) -> h(X)
mark(g(X)) -> ag(X)
mark(h(X)) -> ah(X)
mark(c) -> ac
mark(d) -> d


Strategy:

innermost




Using the Dependency Graph resulted in no new DP problems.
