A Comparative Analysis of Swarm Intelligence Techniques for Feature Selection in Cancer Classification

Pseudocode 2

Pseudocode for CS.

Generate an initial population of 𝑛 host nests;

while (𝑡 < MaxGeneration) or (stop criterion)

 Get a cuckoo randomly (say, 𝑖) and replace its solution by performing Levy flights;

 Evaluate its fitness 𝐹_𝑖

 Choose a nest among 𝑛 (say, 𝑗) randomly;

 if (𝐹_𝑖<𝐹_𝑗)

  Replace 𝑗 by the new solution;

 end if

 A fraction (𝑝_𝑎) 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
