Differential Evolution for Lifetime Maximization of Heterogeneous Wireless Sensor Networks

Pseudocode 2

The pseudocode of recombination operation.

/* recombination operation */

(1)  for  𝑖= 1: popsize  % for every chromosome

   % randomly generates 𝐶_max different integers and

   each integer value belong [1,𝐶_max].

(2)  sequ = randperm(𝐶_max);

   % randomly choose one critical target

(3)   rnum = randint(1,1,[1, numOfCritialTarget]);

   % find the corresponding sensors

(4)   rt =  CritialTargetMatrix(rnum,:);

(5)    for 𝑗= 1: 𝐶_max  % all corresponding sensors

(6)    pop(i,rt(j)) = sequ(j); % recombination

(7)    end for
