We consider the following Problem: Strict Trs: { c(b(a(X))) -> a(a(b(b(c(c(X)))))) , a(X) -> e() , b(X) -> e() , c(X) -> e()} StartTerms: basic terms Strategy: innermost Certificate: YES(?,O(n^1)) Proof: Arguments of following rules are not normal-forms: {c(b(a(X))) -> a(a(b(b(c(c(X))))))} All above mentioned rules can be savely removed.
