Free-Order Online Selection for k-Systems
Kristóf Bérczi, Vasilis Livanos, José A. Soto +1
The paper studies online selection problems on bipartite graphs with combinatorial constraints, introducing k‑growth systems and providing Ω(1/k²)-competitive algorithms for free‑o…
Threshold Dynamics and Correlated Prophet Inequalities
José Correa, Maximilian Fichtl, Reda Jlibene +4
Prophet inequalities have become a central tool for analyzing the performance of online algorithms. However, most existing results assume that input random variables are independen…
About a ball removal process on bins
Jose Correa, José Correa, Marcos Kiwi +3
We consider a basic balls-and-bins question in which you have to distribute balls into bins. Then, round by round, a ball is removed from a non-empty bin chosen uniformly a…
Matroid Secretary via Labeling Schemes
Kristóf Bérczi, Vasilis Livanos, José Soto +1
The Matroid Secretary Problem (MSP) is one of the most prominent settings for online resource allocation and optimal stopping. A decision-maker is presented with a ground set of el…
Posted Pricing and Competition in Large Markets
José Correa, Vasilis Livanos, Dana Pizarro +1
Posted price mechanisms are prevalent in allocating goods within online marketplaces due to their simplicity and practical efficiency. We explore a fundamental scenario where buyer…
Minimization I.I.D. Prophet Inequality via Extreme Value Theory: A Unified Approach
Vasilis Livanos, Ruta Mehta
The I.I.D. Prophet Inequality is a fundamental problem where, given independent random variables drawn from a known distribution , one has to decid…
