Runtime Complexity TRS:
The TRS R consists of the following rules:
a(x1) → x1
a(b(c(x1))) → c(c(a(b(b(x1)))))
b(x1) → 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) → z0
a(b(c(z0))) → c(c(a(b(b(z0)))))
b(z0) → a(z0)
Tuples:
A(b(c(z0))) → c2(A(b(b(z0))), B(b(z0)), B(z0))
B(z0) → c3(A(z0))
S tuples:
A(b(c(z0))) → c2(A(b(b(z0))), B(b(z0)), B(z0))
