From: Group testing via hypergraph factorization applied to COVID-19
Stage 1 tests pools that are formed by cycling through a sequence of pool assignments generated via hypergraph factorization. Putative positives are individuals that are not in any negative pools (decoding). Stage 2 tests the putative positives individually. In this example, n = 12 individuals (2 of whom are actual positives) are each split into q = 2 of m = 6 pools; three are decoded as putative positives and both positives are successfully identified in stage 2.
