Robust Value Maximization in Challenge the Champ Tournaments with Probabilistic Outcomes
Umang Bhaskar, Juhi Chaudhary, Sushmita Gupta +2
Challenge the Champ is a simple tournament format, where an ordering of the players -- called a seeding -- is decided. The first player in this order is the initial champ, and face…
When agents choose bundles autonomously: guarantees beyond discrepancy
Sushmita Gupta, Pallavi Jain, Sanjay Seetharaman +1
We consider the fair division of indivisible items among agents with additive non-negative normalized valuations, with the goal of obtaining high value guarantees, that is, clo…
More Efforts Towards Fixed-Parameter Approximability of Multiwinner Rules
Sushmita Gupta, Pallavi Jain, Souvik Saha +2
Multiwinner Elections have emerged as a prominent area of research with numerous practical applications. We contribute to this area by designing parameterized approximation algorit…
A Simple Algorithm for Combinatorial n-Fold ILPs Using the Steinitz Lemma
Sushmita Gupta, Pallavi Jain, Sanjay Seetharaman +1
We present an algorithm for a class of -fold ILPs whose existing algorithms in literature are often either (1) based on the \textit{augmentation framework} where one starts with…
