Combinatorial Black-box Optimization for Vehicle Design Problem
Ami S. Koshikawa, Masayuki Ohzeki, Masamichi J. Miyama +4
Black-box optimization minimizes an objective function without derivatives or explicit forms. Such an optimization method with continuous variables has been successful in the field…
Solving Inequality-Constrained Binary Optimization Problems on Quantum Annealer
Kouki Yonaga, Masamichi J. Miyama, Masayuki Ohzeki
We propose a new method for solving binary optimization problems under inequality constraints using a quantum annealer. To deal with inequality constraints, we often use slack vari…
Item Listing Optimization for E-commerce Websites based on Diversity
Naoki Nishimura, Kotaro Tanahashi, Koji Suganuma +2
For e-commerce websites, deciding the manner in which items are listed on webpages is an important issue because it can dramatically affect item sales. One of the simplest strategi…
Control of automated guided vehicles without collision by quantum annealer and digital devices
Masayuki Ohzeki, Akira Miki, Masamichi J. Miyama +1
We formulate an optimization problem to control a large number of automated guided vehicles in a plant without collision. The formulation consists of binary variables. A quadratic…
Real-space analysis of scanning tunneling microscopy topography datasets using sparse modeling approach
Masamichi J. Miyama, Koji Hukushima
A sparse modeling approach is proposed for analyzing scanning tunneling microscopy topography data, which contains numerous peaks corresponding to surface atoms. The method, based…
Shear-induced criticality near a liquid-solid transition of colloidal suspensions
Masamichi J. Miyama, Shin-ichi Sasa
We investigate colloidal suspensions under shear flow through numerical experiments. By measuring the time-correlation function of a bond-orientational order parameter, we find a d…
The order-disorder transition in colloidal suspensions under shear flow
Masamichi J. Miyama, Shin-ichi Sasa
We study the order-disorder transition in colloidal suspensions under shear flow by performing Brownian dynamics simulations. We characterize the transition in terms of a statistic…
