A Clustering Approach Using Cooperative Artificial Bee Colony Algorithm

Algorithm 1

Pseudocode for ABC algorithm.

Main steps of the ABC algorithm.

(2.1) cycle=1

(2.2) Initialize the food source positions 𝑥^𝑖, 𝑖=1,…𝑆𝑁

(2.3) Evaluate the nectar amount (fitness function fit_𝑖) of food sources

(4) repeat

(5)  Employed Bees’ Phase

   For each employed bee

     Produce new food source positions 𝑣𝑖

     Calculate the value fit_𝑖

     Apply greedy selection mechanism

   EndFor.

(6)  Calulate the probability values 𝑝_𝑖 for the solution.

(7)  Onlooker Bees’ Phase

   For each onlooker bee

     Chooses a food source depending on 𝑝_𝑖

     Produce new food source positions 𝑣_𝑖

     Calculate the value fit_𝑖

     Apply greedy selection mechanism

   EndFor

(8) Scout Bee Phase

   If there is an employed bee becomes scout

   Then replace it with a new random source positions

(9) Memorize the best solution achieved so far

(10) cycle=cycle+1.

(11) until cycle=Maximum Cycle Number
