Global Particle Swarm Optimization for High Dimension Numerical Functions Analysis

Algorithm 1

The coding for determined IF and updated position in GPSO.

for 𝑖=1∶𝑁

  Ch_iter = fix(rand*𝑡) + 1;

  Ch_part = fix(rand*𝐷) + 1;

while (Ch_part= =𝑖)

   Ch_part = fix(rand*𝐷) + 1;

end;

IF (𝑖,∶,𝑡) = 𝑐₃*rand*(𝐺_best(1, Ch_part, Ch_iter) − X(𝑖,∶,𝑡));

End

V(∶,∶,𝑡+1) = W(t)*V(∶,∶,𝑡) + 𝑐₁*rand*(𝑃_best (∶,∶,𝑡) − X(∶,∶,𝑡))

     + 𝑐₂*rand*(G(∶,∶,𝑡) − X(∶,∶,𝑡)) + IF(∶,∶,𝑡);

Where N: number of iteration, t: current iteration, D: Dimension,

i: particle’s number, X: variable, G: the current gbest result
