Proportionally Fair Matching via Randomized Rounding

Sharmila Duppala, Nathaniel Grammel, Juan Luque +2

Given an edge-colored graph, the goal of the proportional fair matching problem is to find a maximum weight matching while ensuring proportional representation (with respect to the…

On (Random-order) Online Contention Resolution Schemes for the Matching Polytope of (Bipartite) Graphs

Calum MacRury, Will Ma, Nathaniel Grammel

Online Contention Resolution Schemes (OCRS's) represent a modern tool for selecting a subset of elements, subject to resource constraints, when the elements are presented to the al…

The Stochastic Boolean Function Evaluation Problem for Symmetric Boolean Functions

Dimitrios Gkenosis, Nathaniel Grammel, Lisa Hellerstein +1

We give two approximation algorithms solving the Stochastic Boolean Function Evaluation (SBFE) problem for symmetric Boolean functions. The first is an -approximation al…

Improved Guarantees for Offline Stochastic Matching via New Ordered Contention Resolution Schemes

Brian Brubach, Nathaniel Grammel, Will Ma +2

Matching is one of the most fundamental and broadly applicable problems across many domains. In these diverse real-world applications, there is often a degree of uncertainty in the…

Agent Environment Cycle Games

J K Terry, Nathaniel Grammel, Benjamin Black +3

Partially Observable Stochastic Games (POSGs) are the most general and common model of games used in Multi-Agent Reinforcement Learning (MARL). We argue that the POSG model is conc…
