摘要
给定n_1⋅n_2⋅…⋅n_k点G (n_1、甲烷、…,n_k) R ^𝑘这样n_k≥……≥n_2≥n_1∈Z+,我们引入了一种新的算法MΛI,该算法在最小轴对齐的边界框[0,n_1−1]×[0,n_2−1]×内返回一条不相交的覆盖路径…×[0,n_k−1],由3个(n_1⋅n_2⋅…⋅n_k−1)−2个规定长度为n_k−1个单位的链路组成。因此,对于任意n_k≥3,我们的MΛI-algorithm提供的覆盖路径的链接长度小于集合G(n_1,n_2,…,n_k)的基数。进一步,假设k>2,我们给出了G(3,3,…,3)的不交叉覆盖路径,该路径仅包含20*3^(k−3)−2个两个单位长边,该路径受轴向边界框[0,4−√3]×[0,4−√3]×[0,2]×…×[0,2]约束。
GENERAL UNCROSSING COVERING PATHS INSIDE THE AXIS-ALIGNED BOUNDING BOX
Given the finite set of n_1⋅n_2⋅...⋅n_k points G(n_1,n_2,...,n_k) in R^𝑘 such that n_k≥...≥n_2≥n_1∈Z+, we introduce a new algorithm, called MΛI, which returns an uncrossing covering path inside the minimum axis-aligned bounding box [0,n_1−1]×[0,n_2−1]×...×[0,n_k−1], consisting of 3⋅(n_1⋅n_2⋅...⋅n_k−1)−2 links of prescribed length n_k−1 units. Thus, for any n_k≥3, the link length of the covering path provided by our MΛI-algorithm is smaller than the cardinality of the set G(n_1,n_2,...,n_k). Furthermore, assuming k>2, we present an uncrossing covering path for G(3,3,...,3), comprising only 20*3^(k−3)−2 two units long edges, which is constrained by the axis-aligned bounding box [0,4−√3]×[0,4−√3]×[0,2]×...×[0,2].
