1. INTRODUCTION
Group testing is a common strategy employed to identify defective items from a given population of items. The idea of group testing, initiated by Robert Dorfman [1], involves performing tests over subsets of the population instead of tests on individual items to reduce the number of required tests. There is now a renewed interest in group testing to expedite testing for COVID-19 [2]. The objective under the group testing strategy is to outline a sequence of subsets to be tested so that all the defective items can be identified using a minimum possible number of tests.
