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

a(x1) → x1
a(a(b(x1))) → b(b(a(a(x1))))
b(x1) → a(c(a(x1)))

Rewrite Strategy: INNERMOST

(1) CpxTrsToCdtProof (BOTH BOUNDS(ID, ID) transformation)

Converted CpxTRS to CDT

(2) Obligation:

Complexity Dependency Tuples Problem
Rules:

a(z0) → z0
a(a(b(z0))) → b(b(a(a(z0))))
b(z0) → a(c(a(z0)))
Tuples:

A(a(b(z0))) → c2(B(b(a(a(z0)))), B(a(a(z0))), A(a(z0)), A(z0))
B(z0) → c3(A(c(a(z0))), A(z0))
S tuples:

A(a(b(z0))) → c2(B(b(a(a(z0)))), B(a(a(z0))), A(a(z0)), A(z0))

(3) CdtUnreachableProof (EQUIVALENT transformation)

The following tuples could be removed as they are not reachable from basic start terms:

A(a(b(z0))) → c2(B(b(a(a(z0)))), B(a(a(z0))), A(a(z0)), A(z0))
