Convergence, Consensus and Dissensus in the Weighted-Median Opinion Dynamics
Wenjun Mei, Julien M. Hendrickx, Ge Chen +2
Mechanistic and tractable mathematical models play a key role in understanding how social influence shapes public opinions. Recently, a weighted-median mechanism has been proposed…
On the Worst-Case Analysis of Cyclic Coordinate-Wise Algorithms on Smooth Convex Functions
Yassine Kamri, Julien M. Hendrickx, François Glineur
We propose a unifying framework for the automated computer-assisted worst-case analysis of cyclic block coordinate algorithms in the unconstrained smooth convex optimization setup.…
Automated Performance Estimation for Decentralized Optimization via Network Size Independent Problems
Sebastien Colla, Julien M. Hendrickx
We develop a novel formulation of the Performance Estimation Problem (PEP) for decentralized optimization whose size is independent of the number of agents in the network. The PEP…
Resource allocation in open multi-agent systems: an online optimization analysis
Renato Vizuete, Charles Monnoyer de Galland, Julien M. Hendrickx +2
The resource allocation problem consists of the optimal distribution of a budget between agents in a group. We consider such a problem in the context of open systems, where agents…
Random Coordinate Descent for Resource Allocation in Open Multi-Agent Systems
Charles Monnoyer de Galland, Renato Vizuete, Julien M. Hendrickx +2
We propose a method for analyzing the distributed random coordinate descent algorithm for solving separable resource allocation problems in the context of an open multiagent system…
Automatic Performance Estimation for Decentralized Optimization
Sebastien Colla, Julien M. Hendrickx
We present a methodology to automatically compute worst-case performance bounds for a large class of first-order decentralized optimization algorithms. These algorithms aim at mini…
