Krasnosel'skii-Mann iterations beyond asymptotics: a combinatorial analysis

Mario Bravo, Roberto Cominetti

We revisit the classical Krasnosel'skii-Mann fixed point iteration for contractions and nonexpansive maps in general normed spaces. This iteration is ubiquitous across a wide range…

The Increasing Gap Dynamics in a General Spatial Matching Model

Andrés Fielbaum, Roberto Cominetti, José Correa

We study a representation of a problem that appears in numerous transport systems: servers distributed over a given space (e.g., cars on an urban network), receive random reque…

Minimax-optimal Halpern iterations for Lipschitz maps

Mario Bravo, Roberto Cominetti, Jongmin Lee

This paper investigates the minimax-optimality of Halpern fixed-point iterations for Lipschitz maps in general normed spaces. Starting from an a priori bound on the orbit of iterat…

Near-Optimal Sample Complexity for MDPs via Anchoring

Jongmin Lee, Mario Bravo, Roberto Cominetti

We study a new model-free algorithm to compute -optimal policies for average reward Markov decision processes, in the weakly communicating case. Given a generative mod…

Monotonicity of Equilibria in Nonatomic Congestion Games

Roberto Cominetti, Valerio Dose, Marco Scarsini

This paper studies the monotonicity of equilibrium costs and equilibrium loads in nonatomic congestion games, in response to variations of the demands. The main goal is to identify…

The interdependence between hospital choice and waiting time -- with a case study in urban China

Joris van de Klundert, Roberto Cominetti, Yun Liu +1

Hospital choice models often employ random utility theory and include waiting time as a choice determinant. When applied to evaluate health system improvement interventions, these…
