Fishes schooling system

In this work, we consider a group of shes as the particles, but we assumed that only the individuals of its neighbors within a circle sector with central angle φ (is called angle of view) and radius R, are taken into account the average direction of motion. We used a similar model as the well known XY spin model on a square lattice of linear size L, the particles can move freely on the plane (an o-lattice model).

These results have been used to unravel the mysteries of the collective behavior of living systems in nature such as the flocking of birds, schooling of fish, marching of ants and swarming of bees for strategic purposes. While the individual “agents” in these groups possess only local strategic rules and capacity, their collective behavior is characterized by an overlaying order, self-organization, and a collective intelligence that is greater than the sum of the parts.

In the search for a new framework, we have come to believe strongly in emerging management principles based on the “new science” of complexity that exploit an understanding of autonomous human behavior gained from the study of living systems in nature. Specifically, we have begun to build the notion of complex adaptive systems (CAS) into our management assumptions and practices. Complexity scientists have studied the collective behavior of living systems in nature such as the flocking of birds, schooling of fish, marching of ants and the swarming of bees.

Particle swarm optimization (PSO) is a population based stochastic optimization technique influenced by the social behavior of bird flocking or fish schooling.PSO shares many similarities with evolutionary computation techniques such as Genetic Algorithms (GA). The system is initialized with a population of random solutions and searches for optima by updating generations.
