A version of a two-phase simplex technique is given for manually solving those linear-programming problems in which artificial vectors are introduced and subsequently driven out. The first phase of ...

A new method for designing experiments with mixtures has been devised by Scheffé. The fractions of components making up any mixture must add to unity, and hence factor space may be represented by a ...
