An Effective Hybrid Firefly Algorithm with Harmony Search for Global Numerical Optimization

Algorithm 2

Firefly algorithm. FA method.

Begin

  Step  1. Initialization. Set 𝐺=1; define 𝛾; set step size 𝛼 and 𝛽₀ at 𝑟=0.

  Step  2. Evaluate the light intensity I determined by 𝑓(𝑥)

  Step  3.  While  G < MaxGeneration do

       for  𝑖=1 : NP (all NP fireflies) do

         for  𝑗=1 : NP (NP fireflies) do

           if (𝐼_𝑗<𝐼_𝑖),

            move firefly i towards j;

           end if

         Update attractiveness;

         Update light intensity;

         end for  j

       end for  i

       𝐺=𝐺+1;

  Step  4. end while

  Step  5. Output the results.

End.
