Solving Two-Dimensional HP Model by Firefly Algorithm and Simplified Energy Function

Pseudocode 1

The pseudo-codes of the firefly algorithm can be summarized as

Step  1  Initialization.

  Step  1.1  Create the initial population of n fireflies (𝑥₁, 𝑥₂,…, and 𝑥_𝑛) within d-dimensional search space.

  Step  1.2  Formulate light intensity of each firefly so as to be associated with the energy value 𝑓(𝑥).

  Step  1.3  Define the parameters 𝛽₀ and 𝛾.

Step  2  Perform.

while (termination criteria are not met)

  for 𝑖=1 to n

    for j = 1 to 𝑛

      if (𝐼_𝑗<𝐼_𝑖)

        Move firefly 𝑗 towards firefly 𝑖 via (5).

      end if

      Update Attractiveness Table.

      Evaluate New Solutions and Update light intensity.

    end for 𝑗

  end for 𝑖

  Rank the fireflies and find the best.

end for while

Step  3  Post-processing and output.
