Self-Adaptive Step Firefly Algorithm

Pseudocode 1

Pseudocode of the FA.

Begin

 Objective function 𝑓(𝑥),𝑥=(𝑥₁,…,𝑥_𝑑)^𝑇

 Generate initial population of 𝑛 fireflies 𝑥_𝑖,𝑖=1,2,…,𝑛

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

        While (𝑡<MaxGeneration)

   Define absorption coefficient 𝛾

   for 𝑖=1∶𝑛 (𝑛 fireflies)

    for 𝑗=1∶𝑛 (𝑛 fireflies)

     if (𝐼_𝑗>𝐼_𝑖),

       move firefly 𝑖 towards 𝑗

     end if

     Vary attractiveness with distance 𝑟 via exp(−𝛾𝑟^∧2)

     Evaluate new solutions and update light intensity

           end for 𝑗

           end for 𝑖

           Rank the fireflies and find the current best

  end while

  Post-processing the results and visualization
