			== Swarm Intelligence ==

			Systems with [[Swarm Inteliigence\|swarm intelligence]] are to achieve
			an optimal balance between exploration and exploitation.
			During food foraging, colonies and swarms must achieve a good trade-off
			between exploration (search new sources) and exploitation (use known sources).
			Trail-based foraging amont ants and danced-based foraging among honeybees
			allow naturally to regulate the number of foragers:
			if the trail is weak and the food quality low, many ants will lose the
			connection, and start to explore new areas. The weaker the trail, the
			larger is the number of lost ants who are able to discover new food
			sources.
			If the number of dancers in a honeybee colony is low, the unemployed
			foragers will leave the colony and start to explore new areas, too.
			The lower the number of dances, the larger is number of scouts which
			explore new areas.
