The following dependency pairs can be strictly oriented:

Additionally, the following usable rules using the Ce-refinement can be oriented:

mark(app(X1, X2)) -> aapp(mark(X1), mark(X2))

aprefix(L) -> cons(nil, zWadr(L, prefix(L)))
aprefix(X) -> prefix(X)


Used ordering: Polynomial ordering with Polynomial interpretation:

  POL(A__APP(x1, x2))=  x1 + x2  
  POL(MARK(x1))=  x1  
  POL(mark(x1))=  x1

resulting in one new DP problem.
