Group testing algorithm
A group-testing algorithm is said to make an error if it incorrectly labels an item (that is, labels any defective item as non-defective or vice versa). This is not the same thing as the result of a group test being incorrect. An algorithm is called zero-error if the probability that it makes an error is zero. See more In statistics and combinatorial mathematics, group testing is any procedure that breaks up the task of identifying certain objects into tests on groups of items, rather than on individual ones. First studied by Robert Dorfman in … See more Invention and initial progress The concept of group testing was first introduced by Robert Dorfman in 1943 in a short report published in the Notes section of See more The generalised binary-splitting algorithm is an essentially-optimal adaptive group-testing algorithm that finds $${\displaystyle d}$$ or … See more The generality of the theory of group testing lends it to many diverse applications, including clone screening, locating electrical shorts; high speed computer networks; medical examination, quantity searching, statistics; machine learning, DNA … See more Unlike many areas of mathematics, the origins of group testing can be traced back to a single report written by a single person: See more This section formally defines the notions and terms relating to group testing. • The input vector, $${\displaystyle \mathbf {x} =(x_{1},x_{2},\dots ,x_{n})}$$, is defined to be a … See more Non-adaptive group-testing algorithms tend to assume that the number of defectives, or at least a good upper bound on them, is known. This quantity is denoted $${\displaystyle d}$$ in this section. If no bounds are known, there are non-adaptive … See more WebFeb 15, 2024 · Abstract: The group testing problem concerns discovering a small number of defective items within a large population by performing tests on pools of items. …

WebAssumption 1 is a standard assumption made in the group testing literature and should hold provided the individuals being tested approximate a random sample from a larger population. Assumptions 2 and 3 should hold provided the total number of specimens per pool is not too large.

WebDec 11, 2014 · A group testing algorithm is said to be nonadaptive if all the tests can be performed simultaneously (or, in parallel). That is, all the subsets to be tested are specified in advance, and we do not need the test results of some subsets to determine other subsets to be tested. Otherwise, the group testing algorithm is said to be adaptive.
