A Note on Discounted Future Two-Armed Bandits

The Annals of Statistics, 1983
This paper is concerned with the problem of finding Bayes sequential designs for successively choosing between two given Bernoulli variables so as to maximize the total discounted expected sum. Simple hypotheses concerning the success probabilities are assumed and dynamic programming methods are used to characterize optimal designs.

Pragmatic Two‐Stage Design for Clinical Trials With Treatment Selection

Statistics in Medicine, Volume 45, Issue 18-19, August 2026.
ABSTRACT Clinical trials are inherently complex and become more challenging when selecting one treatment from many while also evaluating the efficacy. In this paper, we develop a pragmatic design that balances sample efficiency and practicality through a two‐stage sequential approach.

Bridging Adversarial and Nonstationary Multi-armed Bandit [PDF]

, 2023
In the multi-armed bandit framework, there are two formulations that are commonly employed to handle time-varying reward distributions: adversarial bandit and nonstationary bandit.

Multi-Armed Bandit Approaches for Location Planning with Dynamic Relief Supplies Allocation Under Disaster Uncertainty

Smart Cities
Natural disasters (e.g., floods, earthquakes) significantly impact citizens, economies, and the environment worldwide. Due to their sudden onset, devastating effects, and high uncertainty, it is crucial for emergency departments to take swift action to ...

On the Behavior of Proposers in Ultimatum Games [PDF]

We demonstrate that one should not expect convergence of the proposals to the subgame perfect Nash equilibrium offer in standard ultimatum games. First, imposing strict experimental control of the behavior of the receiving players and focusing on the ...

Two-stage index computation for bandits with switching penalties I : switching costs [PDF]

This paper addresses the multi-armed bandit problem with switching costs. Asawa and Teneketzis (1996) introduced an index that partly characterizes optimal policies, attaching to each bandit state a "continuation index" (its Gittins index) and a ...

Bernoulli two-armed bandits with geometric termination

Stochastic Processes and their Applications, 1981
AbstractThe standard Bernoulli two-armed bandit model is modified by terminating the choice problem after the first unsuccessful trial. Both terminal reward situations and instances in which payoffs accrue with each success are considered. For independent machines, the stay-on-a-winner rule holds in each of these instances.
