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: { a(b(x)) -> a(c(b(x))) } Obligation: innermost runtime complexity Answer: YES(O(1),O(n^1)) We use the processor 'matrix interpretation of dimension 2' to orient following rules strictly. Trs: { a(b(x)) -> a(c(b(x))) } The induced complexity on above rules (modulo remaining rules) is YES(?,O(n^1)) . These rules are moved into the corresponding weak component(s). Sub-proof: ---------- TcT has computed the following constructor-based matrix interpretation satisfying not(EDA) and not(IDA(1)). [a](x1) = [1 2] x1 + [0] [0 0] [1] [b](x1) = [1 0] x1 + [0] [0 0] [2] [c](x1) = [1 0] x1 + [0] [0 0] [0] This order satisfies the following ordering constraints: [a(b(x))] = [1 0] x + [4] [0 0] [1] > [1 0] x + [0] [0 0] [1] = [a(c(b(x)))] We return to the main proof. We are left with following problem, upon which TcT provides the certificate YES(O(1),O(1)). Weak Trs: { a(b(x)) -> a(c(b(x))) } Obligation: innermost runtime complexity Answer: YES(O(1),O(1)) Empty rules are trivially bounded Hurray, we answered YES(O(1),O(n^1))
