An Improved Brain Storm Optimization with Differential Evolution Strategy for Applications of ANNs

Algorithm 1

Pseudocode of the differential evolution operator( ).

()     Begin

()      if rand( ) < _one

()       Select a cluster according to the probabilities based on number of individuals

()       if rand( ) < _one_center

()        execute original operator

()       else

()        execute intra-cluster DE operator to create using formula (8) and (5)

()       endif

()      else

()    Randomly select two clusters

()    if rand( ) < _two_center

()     execute original operator

()    else

()     execute inter-cluster DE operator to create using formula (9) and (5)

()    endif

()   endif
