The following dependency pair can be strictly oriented:

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

Used ordering: Polynomial ordering with Polynomial interpretation:
  POL(S(x1))=  x1  
  POL(ok(x1))=  1 + x1  

resulting in one new DP problem.

Strategy:

The following dependency pair can be strictly oriented:

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

Used ordering: Polynomial ordering with Polynomial interpretation:
  POL(SEL(x1, x2))=  x1  
  POL(mark(x1))=  1 + x1  

resulting in one new DP problem.

Strategy:

The following dependency pair can be strictly oriented:

PROPER(s(X)) -> PROPER(X)


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

Used ordering: Polynomial ordering with Polynomial interpretation:
  POL(PROPER(x1))=  x1  
  POL(dbl(x1))=  x1  
  POL(s(x1))=  1 + x1  

resulting in one new DP problem.
