演講摘要 : We consider optimal group testing of individuals with heterogeneous risks for an infectious disease. Our algorithm significantly reduces the number of tests needed compared to Dorfman (1943). When both low-risk and high-risk samples have sufficiently low infection probability, it is optimal to form heterogeneous groups with exactly one high-risk sample per group. Otherwise, it is never optimal to form heterogeneous groups, but group testing may still be optimal for each risk type. For a range of parameters including the U.S. Covid-19 positivity rate for many periods during the pandemic, the optimal group test size is four.
