Dependency Pair Analysis



R contains the following Dependency Pairs:

F(g(x), y, y) -> F(x, x, y)

Furthermore, R contains one SCC.

Argument Filtering and Ordering


Dependency Pair:

F(g(x), y, y) -> F(x, x, y)


Rule:


f(g(x), y, y) -> g(f(x, x, y))


Strategy:

innermost




The following dependency pair can be strictly oriented:

F(g(x), y, y) -> F(x, x, y)


There are no usable rules for innermost w.r.t. to the AFS that need to be oriented.
Used ordering: Polynomial ordering with Polynomial interpretation:
  POL(g(x1))=  1 + x1  

resulting in one new DP problem.
Used Argument Filtering System:
F(x1, x2, x3) -> x1
g(x1) -> g(x1)

Dependency Graph


Dependency Pair:


Rule:


f(g(x), y, y) -> g(f(x, x, y))


Strategy:

innermost




Using the Dependency Graph resulted in no new DP problems.
