Algorithm 1 Diversity control

Input:  $E_{dim}$: The dimensional entropy of the population in this iteration; $E_{standard}$: The expected entropy of this iteration; Coord: The population  Output:  The new population  1 if $E_{dim}$< $E_{standard}$  2  delete a redundant particle;  3  add a new particle;  4 else if $E_{dim}$> $E_{standard}$  5  delete a worst particle;  6  copy a redundant particle;  7 end
