Multipath Cluster-Assisted Single Station Localization Based on SSA-GA in Outdoor NLOS Environment

Algorithm 2

Genetic algorithm-based improved salp swarm algorithm.

Input

1: Initializing populations

2: while terminate condition has not been met do

3:  fordo

4:   Calculate fitness of salp

5:  end for

6:  =the best search salp

7:  Update

8:  Divide the population into two parts: leaders and followers

9:  fordo

10:   Update the position of the leaders by (10)

11:  end for

12:  fordo

13:   if

14:    Update the position of by (12)

15:   end if

16:  end for

17:  fordo

18:   if

19:    Update the position of the by (11)

20:   end if

21:  end for

22:  Set the population after crossover mutation as

23:  Update populations =combine (,)

24:  Calculate the optimal position of leader

25:  Update the position of the first follower by (13)

26:  fordo

27:   Update the position of followers by (14)

28:  end for

29: end while

Output The best global solution
