Sub-optimality bounds for certainty equivalent policies in partially observed systems
Berk Bozkurt, Aditya Mahajan, Ashutosh Nayyar +1
In this paper, we present a generalization of the certainty equivalence principle of stochastic control. One interpretation of the classical certainty equivalence principle for lin…
Model approximation in MDPs with unbounded per-step cost
Berk Bozkurt, Aditya Mahajan, Ashutosh Nayyar +1
We consider the problem of designing a control policy for an infinite-horizon discounted cost Markov decision process when we only have access to an approximate model…
Optimal Symmetric Strategies in Multi-Agent Systems with Decentralized Information
Sagar Sudhakara, Ashutosh Nayyar
We consider a cooperative multi-agent system consisting of a team of agents with decentralized information. Our focus is on the design of symmetric (i.e. identical) strategies for…
Optimal communication and control strategies in a multi-agent MDP problem
Sagar Sudhakara, Dhruva Kartik, Rahul Jain +1
The problem of controlling multi-agent systems under different models of information sharing among agents has received significant attention in the recent literature. In this paper…
Sufficient statistics for linear control strategies in decentralized systems with partial history sharing
Aditya Mahajan, Ashutosh Nayyar
In decentralized control systems with linear dynamics, quadratic cost, and Gaussian disturbance (also called decentralized LQG systems) linear control strategies are not always opt…
Revenue Maximization in Spectrum Auctions for Dynamic Spectrum Access
Ali Kakhbod, Ashutosh Nayyar, Demosthenis Teneketzis
We investigate revenue maximization problems in auctions for dynamic spectrum access. We consider the frequency division and spread spectrum methods of dynamic spectrum sharing. In…
