YES(O(1),O(n^1)) We are left with following problem, upon which TcT provides the certificate YES(O(1),O(n^1)). Strict Trs: { zeros() -> cons(0(), n__zeros()) , zeros() -> n__zeros() , tail(cons(X, XS)) -> activate(XS) , activate(X) -> X , activate(n__zeros()) -> zeros() } Obligation: innermost runtime complexity Answer: YES(O(1),O(n^1)) We use the processor 'matrix interpretation of dimension 1' to orient following rules strictly. Trs: { zeros() -> cons(0(), n__zeros()) , zeros() -> n__zeros() , activate(X) -> X , activate(n__zeros()) -> zeros() } The induced complexity on above rules (modulo remaining rules) is YES(?,O(n^1)) .
