Term Rewriting System R:
[X, Y, X1, X2]
f(g(X), Y) -> f(X, nf(ng(X), activate(Y)))
f(X1, X2) -> nf(X1, X2)
g(X) -> ng(X)
activate(nf(X1, X2)) -> f(activate(X1), X2)
activate(ng(X)) -> g(activate(X))
activate(X) -> X

Removing Redundant Rules for Innermost Termination



Removing the following rules from R which left hand sides contain non normal subterms

f(g(X), Y) -> f(X, nf(ng(X), activate(Y)))

Removing Redundant Rules



Removing the following rules from R which fullfill a polynomial ordering:

f(X1, X2) -> nf(X1, X2)

where the Polynomial interpretation:
  POL(activate(x1))=  2·x1  
  POL(n__f(x1, x2))=  1 + x1 + x2  
  POL(g(x1))=  x1  
  POL(n__g(x1))=  x1  
  POL(f(x1, x2))=  2 + x1 + x2  
was used.

Not all Rules of R can be deleted, so we still have to regard a part of R.
