From Compensation Design to Budget-Feasible Mechanisms: A Constant Approximation for Subadditive Valuations

Ioannis Anagnostides, Kshipra Bhawalkar, Christopher Liaw +3

Budget-feasible mechanism design is a classic framework introduced by Singer, but there is still a wide gap between existing upper and lower bounds. In this paper, we significantly…

Compensation Design

Ioannis Anagnostides, Kshipra Bhawalkar, Christopher Liaw +5

The paper defines the problem of compensation design, proposing simple cost‑oblivious payment rules that guarantee the existence of pure Nash equilibria with a price of anarchy clo…

The Computational Complexity of Team Zero-Sum Games

Ioannis Anagnostides, Ioannis Panageas, Tuomas Sandholm +1

A celebrated consequence of the minimax theorem is that two-player zero-sum games admit a tractable equilibrium characterization. In many central applications, however, each side c…

Aligning Data-Driven Predictors with Allocation: A Decision-Focused Approach to Survival Analysis

Itai Zilberstein, Ioannis Anagnostides, Tuomas Sandholm

Machine learning predictors have become essential tools for guiding automated decision making. However, a major misalignment persists: predictive models are typically optimized in…

Position: Machine Learning for Heart Transplant Allocation Policy Optimization Should Account for Incentives

Ioannis Anagnostides, Itai Zilberstein, Zachary W. Sollie +2

The allocation of scarce donor organs constitutes one of the most consequential algorithmic challenges in healthcare. While the field is rapidly transitioning from rigid, rule-base…

Swap Regret Minimization Through Response-Based Approachability

Ioannis Anagnostides, Gabriele Farina, Maxwell Fishelson +2

We consider the problem of minimizing different notions of swap regret in online optimization. These forms of regret are tightly connected to correlated equilibrium concepts in gam…
