Suppose a set

has 4 elements,

;For another set

,where n=1,2,...,64, and bis random number in [0.45,0.55]. Select a element from

for each n, and get a select matrix

(64×4), where

represents the nth seletion is ith element in

. So only one element in each column of matrix

is 1, others are 0.

The objective function is

, which means how to select element in

in each n to get objectve function minimum.
