We study a class of cooperative multi-agent optimization problems, where each agent is associated with local action vector and cost, the goal to cooperatively find joint profile that minimizes average costs. consider setting gradient information not readily available, agents only observe their costs incurred by actions as feedback determine new actions. propose zeroth-order scheme provide expli...

background: the aim of this study was to evaluate the effect of filmed modeling in comparison with commonly used tell-show-do technique (t.s.d) on the anxious and cooperative behavior of 4-6 years old children during dental practice. materials and methods: forty six children aged 4-6 years were enrolled in this study and randomly allocated into two groups. group i: at the fi rst visit, the proc...

A wide range of multi-agent coordination problems including reference tracking and disturbance rejection requirements can be formulated as a cooperative output regulation problem. The general framework captures typical problems such as output synchronization, leader-follower synchronization, and many more. In the present paper, we propose a novel distributed regulator for groups of identical an...

In this paper, a feedback reduction scheme has been proposed for multicell cooperative system. Feedback bits are allocated to users by utilizing codebook rotation technique to prevent the waste of feedback resource. Simulation result shows that almost same sum rate can be achieved with less amount of feedback bits.
