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

a(a(a(x1))) → b(x1)
b(c(x1)) → c(c(a(a(a(a(x1))))))

Rewrite Strategy: INNERMOST

(1) CpxTrsMatchBoundsProof (EQUIVALENT transformation)

A linear upper bound on the runtime complexity of the TRS R could be shown with a Match Bound [MATCHBOUNDS1,MATCHBOUNDS2] of 2.
The certificate found is represented by the following graph.
