Shoot-Look-Shoot: A Review and Extension

open access: yesOperations Research, 2004
We consider the optimal use of information in shooting at a collection of targets, generally with the object of maximizing the average number (or value) of targets killed. The shooting problem is viewed as a Markov decision process, and the modal solution technique is stochastic dynamic programming.
