Optimal Dynamic Fees for Blockchain Resources

no code implementations22 Sep 2023 Davide Crapis, Ciamac C. Moallemi, Shouqiao Wang

We develop a general and practical framework to address the problem of the optimal design of dynamic fee mechanisms for multiple blockchain resources.

Automated Market Making and Arbitrage Profits in the Presence of Fees

no code implementations24 May 2023 Jason Milionis, Ciamac C. Moallemi, Tim Roughgarden

We consider the impact of trading fees on the profits of arbitrageurs trading against an automated marker marker (AMM) or, equivalently, on the adverse selection incurred by liquidity providers due to arbitrage.

Automated Market Making and Loss-Versus-Rebalancing

no code implementations11 Aug 2022 Jason Milionis, Ciamac C. Moallemi, Tim Roughgarden, Anthony Lee Zhang

Quantitatively, we illustrate how our model's expressions for LP returns match actual LP returns for the Uniswap v2 WETH-USDC trading pair.

Risk-Sensitive Optimal Execution via a Conditional Value-at-Risk Objective

no code implementations28 Jan 2022 Seungki Min, Ciamac C. Moallemi, Costis Maglaras

As our problem is a special case of a linear-quadratic-Gaussian control problem with a CVaR objective, these results may be interesting in broader settings.

Policy Gradient Optimization of Thompson Sampling Policies

no code implementations30 Jun 2020 Seungki Min, Ciamac C. Moallemi, Daniel J. Russo

We study the use of policy gradient algorithms to optimize over a class of generalized Thompson sampling policies.

Thompson Sampling with Information Relaxation Penalties

1 code implementation NeurIPS 2019 Seungki Min, Costis Maglaras, Ciamac C. Moallemi

With this framework, we define an intuitive family of control policies that include Thompson sampling (TS) and the Bayesian optimal policy as endpoints.

Non-parametric Approximate Dynamic Programming via the Kernel Method

no code implementations NeurIPS 2012 Nikhil Bhat, Vivek Farias, Ciamac C. Moallemi

This paper presents a novel non-parametric approximate dynamic programming (ADP) algorithm that enjoys graceful, dimension-independent approximation and sample complexity guarantees.

A Smoothed Approximate Linear Program

no code implementations NeurIPS 2009 Vijay Desai, Vivek Farias, Ciamac C. Moallemi

We present a novel linear program for the approximation of the dynamic programming cost-to-go function in high-dimensional stochastic control problems.
