YES(?,O(n^1)) 0.00/0.34 YES(?,O(n^1)) 0.00/0.34 0.00/0.34 We are left with following problem, upon which TcT provides the 0.00/0.34 certificate YES(?,O(n^1)). 0.00/0.34 0.00/0.34 Strict Trs: 0.00/0.34 { double(0()) -> 0() 0.00/0.34 , double(s(x)) -> s(s(double(x))) 0.00/0.34 , half(double(x)) -> x 0.00/0.34 , half(0()) -> 0() 0.00/0.34 , half(s(0())) -> 0() 0.00/0.34 , half(s(s(x))) -> s(half(x)) 0.00/0.34 , -(x, 0()) -> x 0.00/0.34 , -(s(x), s(y)) -> -(x, y) 0.00/0.34 , if(0(), y, z) -> y 0.00/0.34 , if(s(x), y, z) -> z } 0.00/0.34 Obligation: 0.00/0.34 innermost runtime complexity 0.00/0.34 Answer: 0.00/0.34 YES(?,O(n^1)) 0.00/0.34 0.00/0.34 The problem is match-bounded by 1. The enriched problem is 0.00/0.34 compatible with the following automaton. 0.00/0.34 { double_0(2) -> 1 0.00/0.34 , double_1(2) -> 4 0.00/0.34 , 0_0() -> 1 0.00/0.34 , 0_0() -> 2 0.00/0.34 , 0_1() -> 1 0.00/0.34 , 0_1() -> 3 0.00/0.34 , 0_1() -> 4 0.00/0.34 , s_0(2) -> 1 0.00/0.34 , s_0(2) -> 2 0.00/0.34 , s_1(3) -> 1 0.00/0.34 , s_1(3) -> 3 0.00/0.34 , s_1(3) -> 4 0.00/0.34 , s_1(4) -> 3 0.00/0.34 , half_0(2) -> 1 0.00/0.34 , half_1(2) -> 3 0.00/0.34 , -_0(2, 2) -> 1 0.00/0.34 , -_1(2, 2) -> 1 0.00/0.34 , if_0(2, 2, 2) -> 1 } 0.00/0.34 0.00/0.34 Hurray, we answered YES(?,O(n^1)) 0.00/0.34 EOF
