Firefly algorithm pseudocode.

---

Begin

(1) Objective function: f (x), x = x1, x2, …, Xn;

(2) Generate an initial population of fireflies

X_i (i = 1, 2, 3).

(3) Formulate light intensity I so that it is associated with f (x)

(for example, for maximization problems, I α f (x) or simply I = f (x);)

(4) Define absorption coefficient γ

 While (t < MaxGeneration)

  for i = 1: n (all n fireflies)

   for j = 1: i (n fireflies)

    if (i, j),

Vary attractiveness with distance r via Exp (−𝛾, 𝑟);

move firefly i towards j;

Evaluate new solutions and update light intensity;

    end if

   end for j

  end for i

Rank fireflies and find the current best;

 end while

Postprocessing the results and visualization;

end
