我们考虑Kannan和Lipton轨道问题的高维版本-在重复应用线性变换A的情况下确定目标向量空间V是否可以从起点x到达目标向量空间V。回答Kannan和Lipton在20世纪80年代提出的两个问题,我们证明了当V有一维时,这个问题在多项式时间内可解,当V有二维或三维时,问题在NPRP中。
We consider higher-dimensional versions of Kannan and Lipton's Orbit Problem---determining whether a target vector space V may be reached from a starting point x under repeated applications of a linear transformation A. Answering two questions posed by Kannan and Lipton in the 1980s, we show that when V has dimension one, this problem is solvable in polynomial time, and when V has dimension two or three, the problem is in NPRP.
