Sorting Balls and Water: Equivalence and Computational Complexity
Takehiro Ito, Jun Kawahara, Shin-ichi Minato +7
Various forms of sorting problems have been studied over the years. Recently, two kinds of sorting puzzle apps are popularized. In these puzzles, we are given a set of bins filled…
Reconfiguration of Spanning Trees with Degree Constraint or Diameter Constraint
Nicolas Bousquet, Takehiro Ito, Yusuke Kobayashi +4
We investigate the complexity of finding a transformation from a given spanning tree in a graph to another given spanning tree in the same graph via a sequence of edge flips. The e…
Fixed-Parameter Algorithms for Graph Constraint Logic
Tatsuhiko Hatanaka, Felix Hommelsheim, Takehiro Ito +3
Non-deterministic constraint logic (NCL) is a simple model of computation based on orientations of a constraint graph with edge weights and vertex demands. NCL captures \PSPACE\xsp…
Reconfiguration of Spanning Trees with Many or Few Leaves
Nicolas Bousquet, Takehiro Ito, Yusuke Kobayashi +4
Let be a graph and be two spanning trees of . We say that can be transformed into via an edge flip if there exist two edges and in $T_2…
Trichotomy for the reconfiguration problem of integer linear systems
Kei Kimura, Akira Suzuki
In this paper, we consider the reconfiguration problem of integer linear systems. In this problem, we are given an integer linear system and two feasible solutions $\boldsymbol…
Decremental Optimization of Dominating Sets Under the Reconfiguration Framework
Alexandre Blanché, Haruka Mizuta, Paul Ouvrard +1
Given a dominating set, how much smaller a dominating set can we find through elementary operations? Here, we proceed by iterative vertex addition and removal while maintaining the…
