(0) Obligation:

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

f(x, f(y, x)) → f(f(x, x), f(a, y))

Rewrite Strategy: INNERMOST

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

Converted CpxTRS to CDT

(2) Obligation:

Complexity Dependency Tuples Problem
Rules:

f(z0, f(z1, z0)) → f(f(z0, z0), f(a, z1))
Tuples:

F(z0, f(z1, z0)) → c(F(f(z0, z0), f(a, z1)), F(z0, z0), F(a, z1))
S tuples:

F(z0, f(z1, z0)) → c(F(f(z0, z0), f(a, z1)), F(z0, z0), F(a, z1))
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(z1, z0)) → c(F(f(z0, z0), f(a, z1)), F(z0, z0), F(a, z1))
