    We consider the exploration problem with a single agent in an undirected graph. The problem requires the agent starting from an arbitrary node to explore all the nodes and edges in the graph and return to the starting node. ...

    A desired property of large distributed systems is self adaptability against the faults that occur more frequently as the size of the distributed system grows. Self-stabilizing protocols provide autonomous recovery from ...
  • Sudo, Yuichi; Ooshita, Fukuhito; Kakugawa, Hirotsugu; Masuzawa, Toshimitsu (Springer, 2014)
    In the population protocol model Angluin et al. proposed in 2004, there exists no self-stabilizing protocol that solves leader election on complete graphs without knowing the exact number of nodes. To circumvent the ...
  • Sudo, Yuichi; Ooshita, Fukuhito; Kakugawa, Hirotsugu; Masuzawa, Toshimitsu (Leibniz International Proceedings in Informatics, 2015)
    In the population protocol model Angluin et al. proposed in 2004, there exists no self-stabilizing leader election protocol for complete graphs, arbitrary graphs, trees, lines, degree-bounded graphs and so on unless the ...
  • Shibata, Masahiro; Kawai, Shinji; Ooshita, Fukuhito; Kakugawa, Hirotsugu; Masuzawa, Toshimitsu (Elsevier, 2015-09-25)
    In this paper, we consider the partial gathering problem of mobile agents in asynchronous unidirectional rings equipped with whiteboards on nodes. The partial gathering problem is a new generalization of the total gathering ...

    プログラミングは一般情報教育において重要な要素の1つである.これまで筆者らは,音センサ,赤外線センサなどを用い,インタラクティブなメディアコンテンツ(インスタレーション)の制作を通して,デジタル技術を表現手段とする造形基礎学習と,プログラミング学習との双方の目的を持つ教育プログラムを構築し,その教材を開発した(SV [Sensory Vision]教育プログラム).受講生が制作するのは,センサからの入力に応答して動的に生成されるグラフィ ...
