Research Contents

A macroscopic structure was analyzed for a system composed of multiple elements the dynamics of which are affected by the distribution of the elements. First, the moment vector equation (MVE) is derived. The average probability density function (pdf) in a steady state is derived using eigen analysis of the coefficient matrix of the MVE. The macroscopic structure of the system and the mechanism that provides the average pdf and the transient response are then analyzed using eigen analysis.

These mothods have been applied to sparse nonlinear optimization problems, and they have been used to solve a recipe optimization problem.

Attractive Factors of My Research

We can obtain not only the transient and stationary properties of the system but also the macroscopic structure and the mechanism providing the properties for arbitrary high-dimensional systems.


My main achievement is journal papers (20 papers).
