Pacing Equilibria in Abstract Mechanisms
Salam Afiouni, Christian Kroer
Digital platforms increasingly rely on automated budget-management systems to regulate participation across allocation opportunities. A common tool is multiplicative pacing, which…
Fully Distributed Tâtonnement for Chores Markets
Bhaskar Ray Chaudhury, Christian Kroer, Ruta Mehta +1
We study price-adjustment dynamics for computing competitive equilibria (CE) in Fisher markets with chores. Unlike in classical goods markets, prices in chores markets are payments…
Tâtonnement Dynamics for Fisher Markets with Chores
Bhaskar Ray Chaudhury, Christian Kroer, Ruta Mehta +1
In this paper, we initiate the study of tâtonnement dynamics in markets with chores. Tâtonnement is a fundamental market dynamics, capturing how prices evolve when they are adjuste…
Colonel Blotto with Battlefield Games
Salam Afiouni, Jakub Cerny, Chun Kai Ling +1
We study a class of two-player zero-sum Colonel Blotto games in which, after allocating soldiers across battlefields, players engage in (possibly distinct) normal-form games on eac…
On the Convergence of Alternating Gradient Descent-Ascent in Bilinear Games
Tianlong Nan, Shuvomoy Das Gupta, Garud Iyengar +1
We study the alternating gradient descent-ascent (AltGDA) algorithm in two-player zero-sum games. Alternating methods, where players take turns to update their strategies, have lon…
Contested Route Planning
Jakub Černý, Garud Iyengar, Christian Kroer
We consider the problem of routing for logistics purposes, in a contested environment where an adversary attempts to disrupt the vehicle along the chosen route. We construct a game…
