WORST_CASE(?,O(n^1)) * Step 1: NaturalMI WORST_CASE(?,O(n^1)) + Considered Problem: - Strict TRS: activate(X) -> X activate(n__f(X)) -> f(X) f(X) -> n__f(X) f(0()) -> cons(0(),n__f(s(0()))) f(s(0())) -> f(p(s(0()))) p(s(0())) -> 0() - Signature: {activate/1,f/1,p/1} / {0/0,cons/2,n__f/1,s/1} - Obligation: innermost runtime complexity wrt. defined symbols {activate,f,p} and constructors {0,cons,n__f,s} + Applied Processor: NaturalMI {miDimension = 1, miDegree = 1, miKind = Algebraic, uargs = UArgs, urules = URules, selector = Nothing} + Details: We apply a matrix interpretation of kind constructor based matrix interpretation: The following argument positions are considered usable: uargs(f) = {1} Following symbols are considered usable: {activate,f,p} TcT has computed the following interpretation: p(0) = [1] p(activate) = [8] x1 + [13] p(cons) = [3] p(f) = [2] x1 + [2] p(n__f) = [1] x1 + [0] p(p) = [10] p(s) = [11] Following rules are strictly oriented: activate(X) = [8] X + [13] > [1] X + [0] = X activate(n__f(X)) = [8] X + [13] > [2] X + [2] = f(X) f(X) = [2] X + [2] > [1] X + [0] = n__f(X) f(0()) = [4] > [3] = cons(0(),n__f(s(0()))) f(s(0())) = [24] > [22] = f(p(s(0()))) p(s(0())) = [10] > [1] = 0() Following rules are (at-least) weakly oriented: WORST_CASE(?,O(n^1))
