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: { and(not(not(x)), y, not(z)) -> and(y, band(x, z), 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: { and(not(not(x)), y, not(z)) -> and(y, band(x, z), 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)). [and](x1, x2, x3) = [1 3] x1 + [1 3] x2 + [3 0] x3 + [1] [2 3] [2 3] [2 0] [1] [not](x1) = [1 0] x1 + [0] [1 0] [1] [band](x1, x2) = [1 0] x1 + [1 0] x2 + [1] [0 0] [0 0] [0] This order satisfies the following ordering constraints: [and(not(not(x)), y, not(z))] = [4 0] x + [1 3] y + [3 0] z + [4] [5 0] [2 3] [2 0] [4] > [4 0] x + [1 3] y + [1 0] z + [2] [4 0] [2 3] [2 0] [3] = [and(y, band(x, z), 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: { and(not(not(x)), y, not(z)) -> and(y, band(x, z), 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))
