Differential Evolution Algorithm with Self-Adaptive Population Resizing Mechanism

Algorithm 3

Population reducing strategy.

(1): Begin

(2):  Arrange the population with its fitness function values in ascending order

(3):  ^→𝐅(𝑓(^→𝑥₁),𝑓(^→𝑥₂),…,𝑓(^→𝑥_𝑆𝑃))=(𝑓_min,𝑓_min+1,…,𝑓_max)

(4):  𝜌₁=⌊𝑠%×𝑁𝑃⌋

(5):  Remove the last 𝜌₁ individuals from current population

(6): End
