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

0(x1) → 1(x1)
4(5(4(5(x1)))) → 4(4(5(5(x1))))
5(5(5(5(5(5(4(4(4(4(4(4(x1)))))))))))) → 2(x1)

Rewrite Strategy: INNERMOST

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

Converted CpxTRS to CDT

(2) Obligation:

Complexity Dependency Tuples Problem
Rules:

0(z0) → 1(z0)
4(5(4(5(z0)))) → 4(4(5(5(z0))))
5(5(5(5(5(5(4(4(4(4(4(4(z0)))))))))))) → 2(z0)
Tuples:

4'(5(4(5(z0)))) → c1(4'(4(5(5(z0)))), 4'(5(5(z0))), 5'(5(z0)), 5'(z0))
S tuples:

4'(5(4(5(z0)))) → c1(4'(4(5(5(z0)))), 4'(5(5(z0))), 5'(5(z0)), 5'(z0))
K tuples:none

(3) CdtUnreachableProof (EQUIVALENT transformation)

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

4'(5(4(5(z0)))) → c1(4'(4(5(5(z0)))), 4'(5(5(z0))), 5'(5(z0)), 5'(z0))

(4) Obligation:
