Research for TMA

In every question of search there are in principle two parts. One involves the targets, and studies their physical characteristics, position, and motion; since the latter are largely unknown to the searcher, a branch of the science of probability is applied, sometimes so simple as to be trivial, at other times involving developments comparable to statistical mechanics. The other part involves the searcher, his capabilities, position, and motion; inasmuch as detection is an event of uncertainties, this part of the question will also appeal to probability, specifically studying the probability laws of detection. The study does not stop there; having gained fundamental knowledge as to these two parts of the question and their interrelation, it is necessary to make application to the tactical matters in which search is an essential component, such as hunts, barriers, and those defensive types of search known as screens. This study treats these questions from the point of view and in the order indicated above. It is intended to be scientific and critical in spirit and mathematical in method.
