Estimation is one of the most important factors in building and designing software systems, to provide a study of the principles of reducing the cost of software and understanding how to apply these techniques to general programs. The swarm intelligence algorithms have been used because they have community-based methods where there is a range of potential solutions in this community. The ideal solution is sought through repetitive steps; these methods are based on solving complex problems by simple factors without central control or a comprehensive model and possess distributed control. The most important characteristics of swarm intelligence are that it will produce a self-contained, adaptive, scalable, flexible, powerful, parallel, self-regulatory and cost-effective system.
