Adaptive Cuckoo Search Algorithm for Unconstrained Optimization

Algorithm 2

Adaptive cuckoo search algorithm.

begin

Generate initial population of host nest ,

Define minimum step size value

Define maximum step size value

for all   do

Evaluate the fitness function

end for

while (iter < MaxGeneration) or (stopping criterion)

Calculate the average fitness value of all the host nests

Find the minimum fitness value among all the host nests

for all host nests do

Current position

Calculate the step size for Lévy flight using (2)

Generate a cuckoo egg from host nest by using Lévy flight

if ( falls outside the bounds) then

Replace with

end if

Calculate the fitness function

if () then

Replace with

Replace with

end if

end for

Abandon a fraction of the worst nests

Build new nests randomly to replace nests lost

Evaluate the fitness of new nests

end while
