A Novel Adaptive Cuckoo Search for Optimal Query Plan Generation

Algorithm 1

Pseudocode for Cuckoo search.
Generate an initial population of host nests;
while () or (stop criterion)
  Get a cuckoo randomly () and replace its solution by performing Levy flights;
  Evaluate its fitness
  Choose a nest among () randomly;
  if ()
    Replace by the new solution;
  end if
  A fraction () of the worse nests is abandoned and new ones are built;
  Keep the best solutions/nests;
  Rank the solutions/nests and find the current best;
  Pass the current best to the next generation;
end while
