Optimized group testing mixing matrix design.
(A-C) Hamming code parity check pooling matrix design for N = 7, 15, and 31. (A) N = 7 numerical matrix with 3 pools (3x7). (B) N = 15 numerical matrix with 4 pools (4x15). (C) N = 31 pixel matrix with 5 pools (5x31). (D) Bipartite pooling matrix design optimized for high N and prevalence rates. N = 40 pixel matrix with 16 pools (16x40). (A,B,C,D) White pixel indicates a sample included in the pool. Black pixel indicates a sample not included in pool.
