The generalised binary-splitting algorithm is an essentially-optimal adaptive group-testing algorithm that finds or fewer defectives among items as follows: 1. If , test the items individually. Otherwise, set and . 2. Test a group of size . If the outcome is negative, every item in the group is declared to be non-defective; set and go to step 1. Otherwise, use a binary search to identify one defective and …
