Used ordering: Polynomial ordering with Polynomial interpretation:
  POL(proper(x1))=  0  
  POL(g(x1))=  0  
  POL(h(x1))=  x1  
  POL(mark(x1))=  1  
  POL(ok(x1))=  0  
  POL(TOP(x1))=  x1  
  POL(f(x1))=  x1  

resulting in one new DP problem.

Dependency Graph


Dependency Pair:


Rules:


active(f(X)) -> mark(g(h(f(X))))
active(f(X)) -> f(active(X))
active(h(X)) -> h(active(X))
f(mark(X)) -> mark(f(X))
f(ok(X)) -> ok(f(X))
h(mark(X)) -> mark(h(X))
h(ok(X)) -> ok(h(X))
proper(f(X)) -> f(proper(X))
proper(g(X)) -> g(proper(X))
proper(h(X)) -> h(proper(X))
g(ok(X)) -> ok(g(X))
top(mark(X)) -> top(proper(X))
top(ok(X)) -> top(active(X))





Using the Dependency Graph resulted in no new DP problems.
