Minimum Test Sets
Jan Karel Lenstra
General Manager, CWI, the Centre for Mathematics and Computer Science
Given a number of items and a collection of subsets, called tests, find a smallest number of tests that enable one to distinguish between each pair of items. I will describe several practical settings in which this problem occurs and discuss a variety of approaches to obtain optimal or approximate solutions. I will make an attempt to put these approaches in a historical context.
