3. Introduction
• Optimization is a technique to find the optimum solution for
any problem.
• We can say optimization is to get maximum from minimum.
• Nature inspired Swarm based Algorithm is recent technique
for optimization in which the algorithms are developed with
the help of nature phenomenon.
• Artificial Bee colony Algorithm is one of the swarm based
algorithm which studies the behaviour of bees in nature.

4. Artificial bee colony algorithm
• The artificial bee colony (ABC) algorithm is a recent
representative of a number of swarm intelligence algorithms
that are inspired by some type of behavior observed in real
bee colonies.[1]
• It was introduced by Karaboga (2005), who applied it to
continuous optimization problems.
• In the ABC algorithm, there are three types of (artificial)
bees, namely employed bees, onlooker bees, and scout
bees.[1]
