Selecting Tests in Diagnostic Keys with Unknown Responses

Abstract

HERE we outline a method for constructing diagnostic keys from test results, some of which are unknown. The method is then modified to reduce the number of different tests used. Elsewhere1 we discuss an application to yeasts, in which the primary purpose is not so much the construction of a key, but to find how few out of a set of tests is required to identify all the yeasts.
