What is Link-State Routing Algorithm

A swarm may be defined as a population of interacting elements that is able to optimize some global objective through collaborative search of a space (Kennedy, 2001). The elements may be very simple machines or very complex living beings, but there are two restrictions to be observed: They are limited to local interactions; usually the interaction is not performed directly but indirectly through the environment. The property that makes swarms interesting is their self-organizing behaviour; in other words, it is the fact that a lot of simple processes can lead to complex results.
