Differential Evolution Algorithm with Self-Adaptive Population Resizing Mechanism

Algorithm 4

Population augmenting strategy1.

(1): Begin

(2):   Select the best individual from the current population

(3):  Randomly select four different vectors 𝑥^𝐺_𝑟1≠𝑥^𝐺_𝑟2≠𝑥^𝐺_𝑟3≠𝑥^𝐺_𝑟4 from the

(4):  current population

(5):  𝑥^𝐺_𝑖,𝑏=𝑥^𝐺_best+𝐹⋅(𝑥^𝐺_𝑟1−𝑥^𝐺_𝑟2)+𝐹⋅(𝑥^𝐺_𝑟3−𝑥^𝐺_𝑟4)

(6):  Store 𝑥^𝐺_𝑖,𝑏 into BA

(7):  Add the individual of BA into the current population

(8):  Empty BA

(9): End
