Runtime Complexity TRS:
The TRS R consists of the following rules:
a(f, a(g, a(f, x))) → a(f, a(g, a(g, a(f, x))))
a(g, a(f, a(g, x))) → a(g, a(f, a(f, a(g, x))))

(3) CdtUnreachableProof (EQUIVALENT transformation)
The following tuples could be removed as they are not reachable from basic start terms:
A(f, a(g, a(f, z0))) → c(A(f, a(g, a(g, a(f, z0)))), A(g, a(g, a(f, z0))), A(g, a(f, z0)), A(f, z0))
