Runtime Complexity TRS:

The TRS R consists of the following rules:

c → f(g(c))

f(g(X)) → g(X)

Rewrite Strategy: FULL

### (1) InfiniteLowerBoundProof (EQUIVALENT transformation)

The loop following loop proves infinite runtime complexity:

The rewrite sequence

c →^{+} f(g(c))

gives rise to a decreasing loop by considering the right hand sides subterm at position [0,0].

The pumping substitution is [ ].

The result substitution is [ ].
