Efficient Segment Folding is Hard
Takashi Horiyama, Fabian Klute, Matias Korman +3
We introduce a computational origami problem which we call the segment folding problem: given a set of line-segments in the plane the aim is to make creases along all segments…
Longest Common Subsequence in Sublinear Space
Masashi Kiyomi, Takashi Horiyama, Yota Otachi
We present the first -space polynomial-time algorithm for computing the length of a longest common subsequence. Given two strings of length , the algorithm runs i…
Derivative structure enumeration using binary decision diagram
Kohei Shinohara, Atsuto Seko, Takashi Horiyama +3
A derivative structure is a nonequivalent substitutional atomic configuration derived from a given primitive cell. The enumeration of derivative structures plays an essential role…
Compiling Crossing-free Geometric Graphs with Connectivity Constraint for Fast Enumeration, Random Sampling, and Optimization
Yu Nakahata, Takashi Horiyama, Shin-ichi Minato +1
Given points in the plane, we propose algorithms to compile connected crossing-free geometric graphs into directed acyclic graphs (DAGs). The DAGs allow efficient counting, enu…
