Runtime Complexity TRS:
The TRS R consists of the following rules:

a__f(f(X)) → a__c(f(g(f(X))))
a__c(X) → d(X)
a__h(X) → a__c(d(X))
mark(f(X)) → a__f(mark(X))
mark(c(X)) → a__c(X)
mark(h(X)) → a__h(mark(X))
mark(g(X)) → g(X)
mark(d(X)) → d(X)
a__f(X) → f(X)
a__c(X) → c(X)
a__h(X) → h(X)

(7) CdtPolyRedPairProof (UPPER BOUND (ADD(O(n^1))) transformation)

Found a reduction pair which oriented the following tuples strictly. Hence they can be removed from S.

MARK(f(z0)) → c7(MARK(z0))
MARK(h(z0)) → c9(MARK(z0))
We considered the (Usable) Rules:none
And the Tuples:

MARK(f(z0)) → c7(MARK(z0))
MARK(h(z0)) → c9(MARK(z0))
The order we found is given by the following interpretation:
Polynomial interpretation :

POL(MARK(x1)) = [4]x1   
POL(c7(x1)) = x1   
POL(c9(x1)) = x1   
POL(f(x1)) = [1] + x1   
POL(h(x1)) = [4] + x1
