Computes the minimum of a number of desirability functions.

`f,...` |
desirability functions |

The Desirability Index was introduced by Harrington (1965), and the concept was extended by Derringer and Suich (1980). It is a means for multicriteria (quality) optimization in industrial quality management. All desirability functions of the quality criteria are combined into a univariate global quality criterion in [0,1] which has to be optimized.

The function can be used for Harrington as well as Derringer and Suich desirability functions.

`minimumDI(f, ...)`

returns a function object of the Minimum
Desirability Index.
