Elements of the Optimal Search Problem

Lawrence Stone defined the elements of the optimal search problem in his 1986 book, Theory of Optimal Search. This was paraphrased extremely well by Cooper, Frost and Robe in their 2003 report – Compatibility of Land SAR Procedures with Search Theory as quoted below; A probability density distribution on search object location and state (so [...]
