Shrimp Feed Formulation via Evolutionary Algorithm with Power Heuristics for Handling Constraints

Algorithm 2

Power Heuristics algorithm.

(i)  Generate uniform random number, between

(ii) Get t using formula:

  where : ingredient value from initial solution, : lower bound of ingredient ,

  : upper bound of ingredient

(iii)  Compare value t with r and determine which one is greater

(iv)  Find new value of by comparing r with t

   If ,

   Then new value of

   If ,

   Then generate new value of by the formula:

(v)  Repeat step (ii) to (iv) for other allele and also for other infeasible individuals

(vi) Calculate new fitness value for the solution
