Literature Review and Theoretical Review of Swarm Intelligence
Introduction
Swarm intelligence (SI) refers to the collective behavior of decentralized, self-organized systems, typically natural or artificial. The concept is inspired by the social behaviors of animals such as birds flocking, fish schooling, and ants foraging. In the context of artificial intelligence and computational problem-solving, SI encompasses algorithms and techniques that simulate these natural behaviors to solve complex optimization and decision-making problems.

Historical Development
The field of swarm intelligence has evolved significantly since its inception. Key milestones in its development include:
[color=var(--tw-prose-bold)]Early Foundations (1980s-1990s):
Ant Colony Optimization (ACO): Introduced by Marco Dorigo in the early 1990s, ACO is inspired by the foraging behavior of ants and is used for solving combinatorial optimization problems.
Particle Swarm Optimization (PSO): Developed by James Kennedy and Russell Eberhart in 1995, PSO is based on the social behavior of birds flocking or fish schooling and is used for continuous optimization problems.
