Fireflies can find groups for data clustering
Autor: Shiho Takamatsu, Toshitsugu Shimoyama, Seiichi Nishihara, Kazunori Mizuno
Publikováno v: ICIT
Data clustering is one of the most important techniques in data analysis. Although the k-means clustering method has been widely used due to its simplicity and easiness of implementation, the performance of the method depends on the initial solution,

Toward systematic generation of 3COL instances based on minimal unsolvable structures
Autor: Kazunori Mizuno, Seiichi Nishihara
Publikováno v: Electronics and Communications in Japan (Part III: Fundamental Electronic Science). 90:27-35
In this paper, the authors propose a method of systematically generating 3-colorable (3COL) graph instances for which a great deal of time and effort are required to obtain a solution (or to determine solvability). This method, which differs from the

Effects of Mn3+ ions on the electrical and magnetic properties of Ca(Mn1−Zr )O3− (0⩽x⩽0.07)
Autor: Hideki Taguchi, Masaru Yoshinaka, Seiichi Nishihara, Ken Hirota, Katsuya Takaoka, Osamu Yamaguchi, Shotaro Morimoto
Publikováno v: Physica B: Condensed Matter. 367:188-194
Perovskite-type Ca(Mn 1− x Zr x )O 3− δ (0⩽ x ⩽0.07) has an orthorhombic GdFeO 3 -type structure with space group Pnma. According to the Rietveld method, the (Mn, Zr)–O distance is independent of x and the (Mn, Zr)–O–(Mn, Zr) angles de
