Differential Evolution Algorithm with Self-Adaptive Population Resizing Mechanism

Algorithm 5

Population augmenting strategy2.

(1): Begin

(2):  𝜌₂=⌈𝑠%×𝑁𝑃⌉

(3):  Select 𝜌₂ best individuals from the current population

(4):  for  𝑖=1 to 𝜌₂  do

(5):   Randomly generate three different vectors 𝑥^𝐺_𝑟1≠𝑥^𝐺_𝑟2≠𝑥^𝐺_𝑟3 from the

(6):   current population

(7):   𝑥^𝐺_𝑖,𝑏=𝑥^𝐺_𝑟1+𝐹⋅(𝑥^𝐺_𝑟2−𝑥^𝐺_𝑟3)

(8):    Store 𝑥^𝐺_𝑖,𝑏 into BA

(9):  end for

(10):  Add the total individuals of BA into the current population, and empty BA

(11): End
