| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | This paper considers a constrained distributed online optimization problem over strongly connected unbalanced directed networks, where a cost function of each agent varies over time. The performance of the proposed method is evaluated by a metric called a regret. We show that a logarithmic regret bound can be achieved by the proposed method with strongly convex cost functions. We illustrate the validity of our method through a numerical example of a distributed estimation of an initial distribution over a diffusion field. |
