(0) Obligation:

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

f(x, f(f(f(a, a), a), a)) → f(f(x, a), x)

Rewrite Strategy: INNERMOST

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

Converted CpxTRS to CDT

(2) Obligation:

Complexity Dependency Tuples Problem
Rules:

f(z0, f(f(f(a, a), a), a)) → f(f(z0, a), z0)
Tuples:

F(z0, f(f(f(a, a), a), a)) → c(F(f(z0, a), z0), F(z0, a))
S tuples:

F(z0, f(f(f(a, a), a), a)) → c(F(f(z0, a), z0), F(z0, a))
K tuples:none
Defined Rule Symbols:

f

Defined Pair Symbols:

F

Compound Symbols:

c

(3) CdtUnreachableProof (EQUIVALENT transformation)

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

F(z0, f(f(f(a, a), a), a)) → c(F(f(z0, a), z0), F(z0, a))

(4) Obligation:

(5) SIsEmptyProof (EQUIVALENT transformation)

The set S is empty
