Artificial Bee Colony (ABC) Algorithm – Matlab Programming

ABC Optimization

For the creation of optimization algorithms that are based on population, different natural phenomena are used. These algorithms have different patterns, but the most common are Swarm talent algorithms and evolution. In this swarm-based technique comes the ABC (artificial bee colony) algorithm. It became simulated via way of bees’ clever foraging conduct. Three components that make the mannequin are:

  • Employed bees
  • Unemployed bees
  • Food resources

Here the main functions of the algorithm of a bee colony are discussed and how they are used in troubleshooting.

When a bee starts searching for a meal, it selects a particular flower. The bee gathers certain information that then needs to be delivered. The information includes the amount of work and effort required to collect that nectar, the distance it needs to travel, and its direction from the nest. 

For conventional profitability of this supply of meals, bee tries to maintain all this information in a single supply. 

Employed bees 

To benefit from the reachable meal source, specific organizations of bees work on it, and these bees are known as employed bees. Bees of such organizations always give the supply of food that is profitable.

Unemployed bees 

Apart from the employed bees, all other bee sets are said to be unemployed bees. These bees have the charge to take all data from the employed bees and summarise the stats. 

These bees consist of 2 groups:

  1. Onlooker bees: These types of bees have the task of collecting all the information of the employed workers of a colony and, after a complete examination, design a source for that colony.
  2. Scouts bees: These scouts’ bees have the task of exploring new sources in the hive.

There are 4 stages in which the ABC algorithm is divided:

  • Segment of Initialization
  • Section of employed bees
  • Incorporation of Scout Bees
  • A phase of onlooker bees

In the segment of Initialization, the ABC method creates a uniformly distributed population depending on the number of input variables, which leads to a possible number of solutions through the optimization problem.

 In the section of employed bees, these bees have the task to alter the contemporary answer that is dependent on the individual research stats and fitness fee. If the new meal source fitness fee is higher than the previous supply of meals, then the bee needs to update the company with the placement of a new one and needs to vanish the old one. Optimization hassle for a precise meal source in the populace.

To clear the hassle of neighbourhood reconfiguration, the algorithm was once used in a radial distribution system (RDS) network. It was used to reduce the power loss and voltage enhancement and balance the feeder load.


In this Matlab project, we explored the four levels of the bees; Initialization, Employment, Onlooking, and Scouting. Then, we discussed a way to implement and follow the ABC set of policies for the objective function. The ABC algorithm is pretty flexible at optimizing mathematical elements and finding the optimal solution for real-world issues.
