MAYBE We are left with following problem, upon which TcT provides the certificate MAYBE. Strict Trs: { quot(x, 0(), s(z)) -> s(quot(x, s(z), s(z))) , quot(0(), s(y), s(z)) -> 0() , quot(s(x), s(y), z) -> quot(x, y, z) } Obligation: innermost runtime complexity Answer: MAYBE We add following weak dependency pairs: Strict DPs: { quot^#(x, 0(), s(z)) -> c_1(quot^#(x, s(z), s(z))) , quot^#(0(), s(y), s(z)) -> c_2() , quot^#(s(x), s(y), z) -> c_3(quot^#(x, y, z)) } and mark the set of starting terms. We are left with following problem, upon which TcT provides the certificate MAYBE. Strict DPs: { quot^#(x, 0(), s(z)) -> c_1(quot^#(x, s(z), s(z))) , quot^#(0(), s(y), s(z)) -> c_2() , quot^#(s(x), s(y), z) -> c_3(quot^#(x, y, z)) } Strict Trs: { quot(x, 0(), s(z)) -> s(quot(x, s(z), s(z))) , quot(0(), s(y), s(z)) -> 0() , quot(s(x), s(y), z) -> quot(x, y, z) } Obligation: innermost runtime complexity Answer: MAYBE No rule is usable, rules are removed from the input problem. We are left with following problem, upon which TcT provides the certificate MAYBE. Strict DPs: { quot^#(x, 0(), s(z)) -> c_1(quot^#(x, s(z), s(z))) , quot^#(0(), s(y), s(z)) -> c_2() , quot^#(s(x), s(y), z) -> c_3(quot^#(x, y, z)) } Obligation: innermost runtime complexity Answer: MAYBE The weightgap principle applies (using the following constant growth matrix-interpretation) The following argument positions are usable: Uargs(c_1) = {1}, Uargs(c_3) = {1} TcT has computed following constructor-restricted matrix interpretation. [0] = [2] [s](x1) = [1] x1 + [0] [quot^#](x1, x2, x3) = [2] x1 + [0] [c_1](x1) = [1] x1 + [1] [c_2] = [1] [c_3](x1) = [1] x1 + [2] This order satisfies following ordering constraints: Further, it can be verified that all rules not oriented are covered by the weightgap condition. We are left with following problem, upon which TcT provides the certificate MAYBE. Strict DPs: { quot^#(x, 0(), s(z)) -> c_1(quot^#(x, s(z), s(z))) , quot^#(s(x), s(y), z) -> c_3(quot^#(x, y, z)) } Weak DPs: { quot^#(0(), s(y), s(z)) -> c_2() } Obligation: innermost runtime complexity Answer: MAYBE The following weak DPs constitute a sub-graph of the DG that is closed under successors. The DPs are removed. { quot^#(0(), s(y), s(z)) -> c_2() } We are left with following problem, upon which TcT provides the certificate MAYBE. Strict DPs: { quot^#(x, 0(), s(z)) -> c_1(quot^#(x, s(z), s(z))) , quot^#(s(x), s(y), z) -> c_3(quot^#(x, y, z)) } Obligation: innermost runtime complexity Answer: MAYBE The input cannot be shown compatible Arrrr..
