A Hybrid Metaheuristic DE/CS Algorithm for UCAV Three-Dimension Path Planning

Algorithm 3

Algorithm of selecting cuckoo for DE/CS.

Begin

  for  𝑖=1 to NP do

    Select uniform randomly 𝑟₁≠𝑟₂≠𝑟₃≠𝑖

     𝑋_𝑣=𝑋_𝑟1+𝐹×(𝑋_𝑟2−𝑋_𝑟3)

     𝑟₄=⌈NP∗rand⌉

    for  𝑗=1 to 𝐷  do

      if rand ≤ CR or 𝑗==𝑟₄ then

         𝑋_𝑢(𝑗)=𝑋_𝑣(𝑗)

      else

         𝑋_𝑢(𝑗)=𝑋_𝑖(𝑗)

      end if

    end for

    if 𝐹(𝑋_𝑢)<𝐹(𝑋_𝑟4)  then

       𝑋_𝑢=𝑋_𝑟4

       𝐹(𝑋_𝑟4)=𝐹(𝑋_𝑢)

    end if

  end for

End.
