  • A note on two geometric paths with few crossings for points labeled by integers in the plane

    Atsuhiro Nakamoto, ODA YOSHIAKI, , Mamoru Watanabe, Tomoki Yamashita

    Discrete Mathematics （Discrete Mathematics)  341 （ 4 ） 1109 - 1113 2018

    Research paper (scientific journal), Joint Work, Accepted,  ISSN  0012365X

    　View Summary

    Let S be a set of n points in the plane in general position such that the integers 1,2,…,n are assigned to the points bijectively. Set h be an integer with 1≤h<n(n+1)∕2. In this paper we consider the problem of finding two vertex-disjoint simple geometric paths consisting of all points of S such that the sum of labels of the points in one path is equal to h and the paths have as few crossings as possible. We prove that there exists such a pair of paths with at most two crossings between them.
