Novel Global Harmony Search Algorithm for Least Absolute Deviation

Algorithm 2

Generating a new harmony by NGHS algorithm.

For each  𝑖∈[1,2,…,𝑁]  do

 𝑥_𝑠=2×𝑥^best_𝑖−𝑥^worst_𝑖

 𝑥_𝑠=min[max(𝑥_𝑠,𝑥_𝑖^𝐿),𝑥_𝑖^𝑈]     //truncation processing

 𝑥^′_𝑖=𝑥^worst_𝑖+rand()×(𝑥_𝑠−𝑥^worst_𝑖)   //position updating

 If  rand()<𝑝_𝑚

    𝑥^′_𝑖=𝑥_𝑖^𝐿+rand()×(𝑥_𝑖^𝑈−𝑥_𝑖^𝐿) //genetic mutation

 End

End
