The Runtime Complexity (innermost) of the given CpxTRS could be proven to be BOUNDS(O(1), O(1)).

(0) Obligation:

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

f(x, y, f(z, u, v)) → f(f(x, y, z), u, f(x, y, v))

Rewrite Strategy: INNERMOST

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

Converted CpxTRS to CDT

(2) Obligation:

Complexity Dependency Tuples Problem
Rules:

f(z0, z1, f(z2, z3, z4)) → f(f(z0, z1, z2), z3, f(z0, z1, z4))

Tuples:

F(z0, z1, f(z2, z3, z4)) → c(F(f(z0, z1, z2), z3, f(z0, z1, z4)), F(z0, z1, z2), F(z0, z1, z4))

S tuples:

F(z0, z1, f(z2, z3, z4)) → c(F(f(z0, z1, z2), z3, f(z0, z1, z4)), F(z0, z1, z2), F(z0, z1, z4))

(3) CdtUnreachableProof (EQUIVALENT transformation)

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

F(z0, z1, f(z2, z3, z4)) → c(F(f(z0, z1, z2), z3, f(z0, z1, z4)), F(z0, z1, z2), F(z0, z1, z4))

(4) Obligation:

Complexity Dependency Tuples Problem
Rules:

f(z0, z1, f(z2, z3, z4)) → f(f(z0, z1, z2), z3, f(z0, z1, z4))

Tuples:none
S tuples:none
K tuples:none
Defined Rule Symbols:
