We are left with following problem, upon which TcT provides the certificate YES(O(1),O(1)). Strict Trs: { not(x) -> xor(x, true()) , implies(x, y) -> xor(and(x, y), xor(x, true())) , or(x, y) -> xor(and(x, y), xor(x, y)) , =(x, y) -> xor(x, xor(y, true())) } Obligation: innermost runtime complexity Answer: YES(O(1),O(1)) We add the following weak dependency pairs: Strict DPs: { not^#(x) -> c_1() , implies^#(x, y) -> c_2() , or^#(x, y) -> c_3() , =^#(x, y) -> c_4() } and mark the set of starting terms. We are left with following problem, upon which TcT provides the certificate YES(O(1),O(1)). Strict DPs: { not^#(x) -> c_1() , implies^#(x, y) -> c_2() , or^#(x, y) -> c_3() , =^#(x, y) -> c_4() } Strict Trs: { not(x) -> xor(x, true()) , implies(x, y) -> xor(and(x, y), xor(x, true())) , or(x, y) -> xor(and(x, y), xor(x, y)) , =(x, y) -> xor(x, xor(y, true())) } Obligation: innermost runtime complexity Answer: YES(O(1),O(1)) No rule is usable, rules are removed from the input problem. We are left with following problem, upon which TcT provides the certificate YES(O(1),O(1)). Strict DPs: { not^#(x) -> c_1() , implies^#(x, y) -> c_2() , or^#(x, y) -> c_3() , =^#(x, y) -> c_4() } Obligation: innermost runtime complexity Answer: YES(O(1),O(1)) The weightgap principle applies (using the following constant growth matrix-interpretation) The following argument positions are usable: none TcT has computed the following constructor-restricted matrix interpretation. [not^#](x1) = [1] [0] [c_1] = [0] [0] [implies^#](x1, x2) = [0] [2] [c_2] = [0] [0] [or^#](x1, x2) = [0] [0] [c_3] = [0] [0] [=^#](x1, x2) = [0] [0] [c_4] = [0] [0] The order satisfies the following ordering constraints: [not^#(x)] = [1] [0] > [0] [0] = [c_1()] [implies^#(x, y)] = [0] [2] >= [0] [0] = [c_2()] [or^#(x, y)] = [0] [0] >= [0] [0] = [c_3()] [=^#(x, y)] = [0] [0] >= [0] [0] = [c_4()] 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 YES(O(1),O(1)). Strict DPs: { implies^#(x, y) -> c_2() , or^#(x, y) -> c_3() , =^#(x, y) -> c_4() } Weak DPs: { not^#(x) -> c_1() } Obligation: innermost runtime complexity Answer: YES(O(1),O(1)) We estimate the number of application of {1,2,3} by applications of Pre({1,2,3}) = {}. Here rules are labeled as follows: DPs: { 1: implies^#(x, y) -> c_2() , 2: or^#(x, y) -> c_3() , 3: =^#(x, y) -> c_4() , 4: not^#(x) -> c_1() } We are left with following problem, upon which TcT provides the certificate YES(O(1),O(1)). Weak DPs: { not^#(x) -> c_1() , implies^#(x, y) -> c_2() , or^#(x, y) -> c_3() , =^#(x, y) -> c_4() } Obligation: innermost runtime complexity Answer: YES(O(1),O(1)) The following weak DPs constitute a sub-graph of the DG that is closed under successors. The DPs are removed. { not^#(x) -> c_1() , implies^#(x, y) -> c_2() , or^#(x, y) -> c_3() , =^#(x, y) -> c_4() } We are left with following problem, upon which TcT provides the certificate YES(O(1),O(1)). Rules: Empty Obligation: innermost runtime complexity Answer: YES(O(1),O(1)) Empty rules are trivially bounded Hurray, we answered YES(O(1),O(1))
