Solving Coupled Composite Monotone Inclusions by Successive Fejér Approximations of Their Kuhn-Tucker Set
Abdullah Alotaibi, Patrick L. Combettes, N. Shahzad
We propose a new class of primal-dual Fejer monotone algorithms for solving systems of com- posite monotone inclusions. Our construction is inspired by a framework used by Eckstein…
Impact of information cost and switching of trading strategies in an artificial stock market
Yi-Fang Liu, Wei Zhang, Chao Xu +2
This paper studies the switching of trading strategies and its effect on the market volatility in a continuous double auction market. We describe the behavior when some uninformed…
Graph-Based Approaches to Clustering Network-Constrained Trajectory Data
Mohamed Khalil El Mahrsi, Fabrice Rossi
Clustering trajectory data attracted considerable attention in the last few years. Most of prior work assumed that moving objects can move freely in an euclidean space and did not…
Playing with parameters: structural parameterization in graphs
Nicolas Bourgeois, Konrad K. Dabrowski, Marc Demange +1
When considering a graph problem from a parameterized point of view, the parameter chosen is often the size of an optimal solution of this problem (the "standard" parameter). A nat…
Existence and regularity of solution for a Stochastic Cahn-Hilliard/Allen-Cahn equation with unbounded noise diffusion
Dimitra C. Antonopoulou, Geogia Karali, Annie Millet
The Cahn-Hilliard/Allen-Cahn equation with noise is a simplified mean field model of stochastic microscopic dynamics associated with adsorption and desorption-spin flip mechanisms…
Variational Bayes model averaging for graphon functions and motif frequencies inference in W-graph models
P. Latouche, S Robin
W-graph refers to a general class of random graph models that can be seen as a random graph limit. It is characterized by both its graphon function and its motif frequencies. In th…
