Algorithm 2. Quadratic interpolation (QI)

Input:

gbest: global optimum position

x: Matrix of population information

Output:

x*: Matrix of newly generated stock information

1.       For  i = 1:size(x)

2.       k  = randperm(N, 2)%Two non-repeating individuals were randomly generated.

3.       The positional information of the new individual is calculated by substituting the three individuals k(1), k(2), and gbest into Equation (5).

4.       End

Return x*
