Multi-Armed Bandits and the Gittins Index - Cornell …
The Gittins index is a measure of the reward that can be achieved through a given stochastic process with certain properties, namely: the process has an ultimate termination state and evolves with an option, at each intermediate state, of terminating. Upon terminating at a given state, the reward … See more To illustrate the theory we can take two examples from a developing sector, such as from electricity generating technologies: wind power and wave power. If we are presented with the two technologies when they are both … See more Questions about the optimal stopping policies in the context of clinical trials have been open from the 1940s and in the 1960s a few … See more In queueing theory, Gittins index is used to determine the optimal scheduling of jobs, e.g., in an M/G/1 queue.
