Dependency Pair Analysis



R contains the following Dependency Pairs:

AMINUS(s(X), s(Y)) -> AMINUS(X, Y)
AGEQ(s(X), s(Y)) -> AGEQ(X, Y)
ADIV(s(X), s(Y)) -> AIF(ageq(X, Y), s(div(minus(X, Y), s(Y))), 0)
ADIV(s(X), s(Y)) -> AGEQ(X, Y)
AIF(true, X, Y) -> MARK(X)
AIF(false, X, Y) -> MARK(Y)
MARK(minus(X1, X2)) -> AMINUS(X1, X2)
MARK(geq(X1, X2)) -> AGEQ(X1, X2)
MARK(div(X1, X2)) -> ADIV(mark(X1), X2)
MARK(div(X1, X2)) -> MARK(X1)
MARK(if(X1, X2, X3)) -> AIF(mark(X1), X2, X3)
MARK(if(X1, X2, X3)) -> MARK(X1)
MARK(s(X)) -> MARK(X)

Furthermore, R contains three SCCs.

Strategy:

innermost




The following dependency pair can be strictly oriented:

AMINUS(s(X), s(Y)) -> AMINUS(X, Y)


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

Used ordering: Polynomial ordering with Polynomial interpretation:
  POL(A__MINUS(x1, x2))=  x1  
  POL(s(x1))=  1 + x1  

resulting in one new DP problem.
