Rerouting Planar Curves and Disjoint Paths

Takehiro Ito, Yuni Iwamasa, Naonori Kakimura +5

In this paper, we consider a transformation of disjoint paths in a graph. For a graph and a pair of disjoint paths and connecting the same set o…

On Reachable Assignments under Dichotomous Preferences

Takehiro Ito, Naonori Kakimura, Naoyuki Kamiyama +4

We consider the problem of determining whether a target item assignment can be reached from an initial item assignment by a sequence of pairwise exchanges of items between agents.…

Online Task Assignment Problems with Reusable Resources

Hanna Sumita, Shinji Ito, Kei Takemura +4

We study online task assignment problem with reusable resources, motivated by practical applications such as ridesharing, crowdsourcing and job hiring. In the problem, we are given…

Monotone edge flips to an orientation of maximum edge-connectivity à la Nash-Williams

Takehiro Ito, Yuni Iwamasa, Naonori Kakimura +6

We initiate the study of -edge-connected orientations of undirected graphs through edge flips for . We prove that in every orientation of an undirected -edge-conne…

Dynamic Bipartite Matching Market with Arrivals and Departures

Naonori Kakimura, Donghao Zhu

In this paper, we study a matching market model on a bipartite network where agents on each side arrive and depart stochastically by a Poisson process. For such a dynamic model, we…

Near-Optimal Regret Bounds for Contextual Combinatorial Semi-Bandits with Linear Payoff Functions

Kei Takemura, Shinji Ito, Daisuke Hatano +4

The contextual combinatorial semi-bandit problem with linear payoff functions is a decision-making problem in which a learner chooses a set of arms with the feature vectors in each…
