Whittle Index for Partially Observed Binary Markov Decision Processes
IEEE Transactions on Automatic Control, 2017We consider the problem of dynamically scheduling $M$ out of $N$ binary Markov chains when only noisy observations of state are available, with ergodic (equivalently, long run average) reward. By passing on to the equivalent problem of controlling the conditional distribution of state given observations and controls, it is cast as a restless ...

Whittle Index for AoI-Aware Scheduling
2020 International Conference on COMmunication Systems & NETworkS (COMSNETS), 2020We consider a system consisting of multiple sensors that send updates to a monitoring station via a shared communication channel. The focus is on designing scheduling policies to minimize the time-average of the weighted sum of the Age-of-Information of the sensors.

A Novel Implementation of Q-Learning for the Whittle Index
2021We develop a method for learning index rules for multi-armed bandits, restless bandits, and dynamic resource allocation where the underlying transition probabilities and reward structure of the system is not known. Our approach builds on an understanding of both stochastic optimisation (specifically, the Whittle index) and reinforcement learning ...

Whittle-indexability of the Cow Path Problem
Proceedings of the 2010 American Control Conference, 2010In this paper we consider the well-studied Cow Path Problem (CPP), an on-line search problem that is typically treated with competitive analysis. This paper uses an alternative approach, posing the problem as a Markov Decision Problem (MDP). Our technical contribution is to prove that when posed as an MDP, a slightly relaxed version of the problem is ...

Restless bandits with controlled restarts: Indexability and computation of Whittle index
2019 IEEE 58th Conference on Decision and Control (CDC), 2019Motivated by applications in machine repair, queueing, surveillance, and clinic care, we consider a scheduling problem where a decision maker can reset m out of n Markov processes at each time. Processes that are reset, restart according to a known probability distribution and processes that are not reset, evolve in a Markovian manner.
