A Unifying Theory of Search
What a grand sounding title for a post? I couldn’t think of another title that summed up what I was hoping to achieve with the post. I’d like to try to explain how all search is linked. Each type of search contains the same elements, but depending on their quantity / use depends on how [...]

Calculating Probability Density Distribution for Missing Person Search
The first of the four elements of the optimal search problem is having a probability density distribution (predicting the likelihood that an object is in any particular search area or region.) To achieve this during a Maritime Search and Rescue Incident one takes into account the accuracy of the initial location report, the current, wind [...]

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 [...]
