Runtime Complexity TRS:
The TRS R consists of the following rules:
a(x1) → b(x1)
b(b(a(c(x1)))) → a(c(c(a(b(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) → b(z0)
b(b(a(c(z0)))) → a(c(c(a(b(a(z0))))))
Tuples:
A(z0) → c1(B(z0))
B(b(a(c(z0)))) → c2(A(c(c(a(b(a(z0)))))), A(b(a(z0))), B(a(z0)), A(z0))
S tuples:
A(z0) → c1(B(z0))
B(b(a(c(z0)))) → c2(A(c(c(a(b(a(z0)))))), A(b(a(z0))), B(a(z0)), A(z0))
K tuples:none
Defined Rule Symbols:
a, b
Defined Pair Symbols:

(3) CdtUnreachableProof (EQUIVALENT transformation)
The following tuples could be removed as they are not reachable from basic start terms:
B(b(a(c(z0)))) → c2(A(c(c(a(b(a(z0)))))), A(b(a(z0))), B(a(z0)), A(z0))
