An analysis of load-balancing algorithms on edge-Markovian evolving graphs

Takeharu Shiraga, Shuji Kijima

Analysis of algorithms on time-varying networks (often called evolving graphs) is a modern challenge in theoretical computer science. The edge-Markovian is a relatively simple and…

How Many Vertices Does a Random Walk Miss in a Network with Moderately Increasing the Number of Vertices?

Shuji Kijima, Nobutaka Shimizu, Takeharu Shiraga

Real networks are often dynamic. In response to it, analyses of algorithms on {\em dynamic networks} attract more and more attentions in network science and engineering. Random wal…

Any Finite Distributive Lattice is Isomorphic to the Minimizer Set of an -Concave Set Function

Tomohito Fujii, Shuji Kijima

Submodularity is an important concept in combinatorial optimization, and it is often regarded as a discrete analog of convexity. It is a fundamental fact that the set of minimizers…

Exploration of Finite 2D Square Grid by a Metamorphic Robotic System

Keisuke Doi, Yukiko Yamauchi, Shuji Kijima +1

We consider exploration of finite 2D square grid by a metamorphic robotic system consisting of anonymous oblivious modules. The number of possible shapes of a metamorphic robotic s…

Finding Submodularity Hidden in Symmetric Difference

Junpei Nakashima, Yukiko Yamauchi, Shuji Kijima +1

A set function on a finite set is submodular if for any pair . The symmetric difference transformation (SD-tr…

Can Walker Localize The Middle Point of A Line-segment?

Akihiro Monde, Yukiko Yamauchi, Shuji Kijima +1

This paper poses a question about a simple localization problem. The question is if an {\em oblivious} walker on a line-segment can localize the middle point of the line-segment in…
