Evolutionary Algorithm with Roulette-Tournament Selection for Solving Aquaculture Diet Formulation

Algorithm 3

Algorithm for roulette-tournament selection.

While population size < pop_size  do

   Generate pop_size random number r

   Calculate cumulative fitness, total fitness () and sum of proportional fitness (Sum)

   Spin the wheel pop_size times

   If  Sum <   then

    Select the first chromosome, otherwise, select th chromosome

   End If

End While

For chromosome to pop_size

   Choose two chromosomes randomly from list of selected chromosome

   If fitness chromosome 1 > fitness chromosome 2

    Select chromosome 1, otherwise, select chromosome 2

   End If

End For
