Biogeography-Based Optimization with Orthogonal Crossover

Algorithm 2

Procedure of mutation operator.

(1) Begin

(2) For  𝑘=1 to Dim

(3)  Use 𝜆_𝑘 and 𝜇_𝑘 to compute the probability 𝑝_𝑘

(4)  Select variable 𝑋_𝑖𝑘 with probability 𝑝_𝑘

(5)  If  𝑋_𝑖𝑘 is selected

(6)   Replace 𝑋_𝑖𝑘 with a randomly generated SIV

(7)  EndIf

(8) EndFor

(9) End
