We propose two novel dynamic event-triggered control laws to solve the average consensus problem for first-order continuous-time multiagent systems over undirected graphs. Compared with most existing triggering laws, proposed involve internal variables, which play an essential role in guaranteeing that time sequence does not exhibit Zeno behavior. Moreover, some are special cases of ours. For self-triggered algorithm, continuous agent listening is avoided as each predicts its next and...

This paper considers distributed online optimization with time-varying coupled inequality constraints. The global objective function is composed of local convex cost and regularization functions the constraint sum functions. A primal-dual dynamic mirror descent algorithm proposed to solve this problem, where cost, regularization, are held privately revealed only after each time slot. Without assuming Slater's condition, we first derive regret violation bounds for show how they depend on...

In this paper, we propose a fully distributed algorithm for second-order continuous-time multi-agent systems to solve the optimization problem. The global objective function is sum of private cost functions associated with individual agents and interaction between described by weighted undirected graph. We show exponential convergence proposed if underlying graph connected, each locally gradient-Lipschitz-continuous, restricted strongly convex respect minimizer. Moreover, reduce overall need...
Distributed bandit online convex optimization with time-varying coupled inequality constraints is considered, motivated by a repeated game between group of learners and an adversary. The attempt to minimize sequence global loss functions at the same time satisfy constraint functions, where are across distributed each round. sum local respectively, which adaptively generated revealed in manner, i.e., only values sampling instance, function held privately learner.

This paper mainly investigates consensus problem with a pull-based event-triggered feedback control. For each agent, the diffusion coupling feedbacks are based on states of its in-neighbors at latest triggering time, and next time this agent is determined by in-neighbors' information. The general directed topologies, including irreducible reducible cases, investigated. scenario distributed continuous communication considered first. It proved that if network topology has spanning tree, then...
This article investigates distributed online convex optimization in the presence of an aggregative variable without any global/central coordinators over a multiagent network. In this problem, each individual agent is only able to access partial information time-varying global loss functions, thus requiring local exchanges between neighboring agents. Motivated by many applications reality, considered functions depend not on their own decision variables, but also variable, such as average all...

Under condition underlying graph is undirected and connected, it proven together protocol make state each agent converges exponentially average agents' initial states....

We first consider first-order primal–dual algorithm. show that it converges sublinearly to stationary point if each is smooth and linearly optimum under an additional condition satisfies Polyak–Łojasiewicz condition. weaker than strong convexity, which standard for proving linear convergence algorithms, minimizer not necessarily...
In this paper, we consider the distributed optimization problem, whose objective is to minimize global function, which sum of local convex functions, by using information exchange. To avoid continuous communication among agents, propose a algorithm with dynamic event-triggered mechanism. We show that scheme converges minimizer exponentially, if underlying graph undirected and connected. Moreover, free Zeno behavior. For particular case, also explicitly characterize lower bound for...

At each round, agent selects from set, then only portion function coordinate block at this round are privately revealed to agent. The goal minimize network-wide accumulated time. Two algorithms full-information bandit feedback proposed. Both dynamic static regret bounds...
Nonlinearities are present in all real applications. Two types of general nonlinear consensus protocols considered this paper, namely, the systems with communication and actuator constraints. The solutions understood sense Filippov to handle possible discontinuity controllers. For each case, we prove asymptotic stability minimal assumptions on nonlinearity, for both directed undirected graphs. These results extend literature more dynamics topologies. As applications established theorems,...
This paper presents the formulation and analysis of a fully distributed dynamic event-triggered communication based robust average consensus algorithm. Dynamic problem involves networked set agents estimating time-varying reference signals locally available to individual agents. We propose an asymptotically stable solution that is network disruptions. Since this algorithm requires continuous among agents, we introduce novel scheme reduce overall inter-agent communications. It shown free Zeno...

Noting that information compression is a key tool to reduce heavy communication load for algorithms as agents iteratively communicate neighbors, propose three primal–dual compressed communication. The first two are applicable general class of compressors bounded relative error and third algorithm suitable classes absolute error. We show proposed have comparable convergence properties...
