我们提出了一种用于有限域约束求解的量子算法,其中约束的数量为 2。它是完整的,运行时间为 O((d/2) n/2 ),其中 d 是变量域的大小,n 是变量的数量。对于 d = 3 的情况,我们提供了一种获得时间上限 O(8 n/8 ) ≃ O(1.2968 n ) 的方法。此外,对于 d = 5,上限也得到了改进。以稍微不同的方式使用此方法,我们可以在 O(1.2185 n ) 时间内确定 3-可色性。
We present a quantum algorithm for finite domain constraint solving, where the constraints have arity 2. It is complete and runs in O((d/2) n/2 ) time, where d is size of the domain of the variables and n the number of variables. For the case of d = 3 we provide a method to obtain an upper time bound of O(8 n/8 ) ≃ O(1.2968 n ). Also for d = 5 the upper bound has been improved. Using this method in a slightly different way we can decide 3-colourability in O(1.2185 n ) time.
