Planning Optimization of the Distributed Antenna System in High-Speed Railway Communication Network Based on Improved Cuckoo Search

Algorithm 1

ICSDC.

Input:

 : objective function determined by practical problems

 : initial solutions of host nests;

 while do

  Lévy flights to get random cuckoo;

  Updating the solutions according the random cuckoo;

  Evaluate its quality/fitness ;

  for each nest among do

   if then

    replace by the new solution;

   end if

  end for

  for each nest among host nests do

   if then

    Abandon the current nest and rebuild new nest by

    dimensional evolution mechanism;

   end if

  end for

  Evaluate its quality/fitness ;

  for each nest among do

   if then

    replace by the new solution;

   end if

  end for

  Find the current best ;
