     ↳Dependency Pair Analysis



R contains the following Dependency Pairs:

AF(g(X), Y) -> AF(mark(X), f(g(X), Y))
AF(g(X), Y) -> MARK(X)
MARK(f(X1, X2)) -> AF(mark(X1), X2)
MARK(f(X1, X2)) -> MARK(X1)
MARK(g(X)) -> MARK(X)

Furthermore, R contains one SCC.

On this DP problem, a Forward Instantiation SCC transformation can be performed.
As a result of transforming the rule

MARK(g(g(X''))) -> MARK(g(X''))
11 new Dependency Pairs are created:

Dependency Pairs:

MARK(f(f(f(f(f(X1''''', X2'''''''), X2''0'''), X2'''''), X2''''), X2)) -> MARK(f(f(f(f(X1''''', X2'''''''), X2''0'''), X2'''''), X2''''))
MARK(f(f(f(f(X1'''', X2'''''), X2''0'), X2'''), X2)) -> MARK(f(f(f(X1'''', X2'''''), X2''0'), X2'''))
MARK(f(f(f(f(X1''', X2'''''), X2''0'), X2''), X2)) -> MARK(f(f(f(X1''', X2'''''), X2''0'), X2''))
MARK(f(f(f(X1'''', X2'''''), X2''''), X2)) -> MARK(f(f(X1'''', X2'''''), X2''''))
MARK(f(f(f(f(g(X'''''), X2''''''), X2'''0), X2''''), X2)) -> MARK(f(f(f(g(X'''''), X2''''''), X2'''0), X2''''))


Rules:


af(g(X), Y) -> af(mark(X), f(g(X), Y))
af(X1, X2) -> f(X1, X2)
mark(f(X1, X2)) -> af(mark(X1), X2)
mark(g(X)) -> g(mark(X))


Strategy:

innermost




The following dependency pairs can be strictly oriented:

MARK(f(f(f(f(f(X1''''', X2'''''''), X2''0'''), X2'''''), X2''''), X2)) -> MARK(f(f(f(f(X1''''', X2'''''''), X2''0'''), X2'''''), X2''''))
MARK(f(f(f(f(X1'''', X2'''''), X2''0'), X2'''), X2)) -> MARK(f(f(f(X1'''', X2'''''), X2''0'), X2'''))
MARK(f(f(f(f(X1''', X2'''''), X2''0'), X2''), X2)) -> MARK(f(f(f(X1''', X2'''''), X2''0'), X2''))
MARK(f(f(f(X1'''', X2'''''), X2''''), X2)) -> MARK(f(f(X1'''', X2'''''), X2''''))
MARK(f(f(f(f(g(X'''''), X2''''''), X2'''0), X2''''), X2)) -> MARK(f(f(f(g(X'''''), X2''''''), X2'''0), X2''''))


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

Used ordering: Polynomial ordering with Polynomial interpretation:
  POL(MARK(x1))=  1 + x1  
  POL(g(x1))=  0  
  POL(f(x1, x2))=  1 + x1  

resulting in one new DP problem.
