In numerical analysis, hill climbing is a mathematical optimization technique which belongs to the family of local search. It is an iterative algorithm that starts with an arbitrary solution to a problem, then attempts to find a better solution by making an incremental change to the solution.

Examples of swarm intelligence in natural systems include ant colonies, bee colonies, bird flocking, hawks hunting, animal herding, bacterial growth, fish schooling and microbial intelligence. The application of swarm principles to robots is called swarm robotics while swarm intelligence refers to the more general set of algorithms.
Stochastic hill climbing is a variant of the basic hill climbing method. While basic hill climbing always chooses the steepest uphill move, "stochastic hill climbing chooses at random from among the uphill moves; the probability of selection can vary with the steepness of the uphill move."
Jessiko robot fish on France Pavilion at Yeosu 2012 World Expo. A robot fish is a type of bionic robot that has the shape and locomotion of a living fish.Most robot fish are designed to emulate living fish which use body-caudal fin (BCF) propulsion, and can be divided into three categories: single joint (SJ), multi-joint (MJ) and smart material-based "soft-body" design.
Anabas cobojius, the Gangetic koi, popularly known as Koi in Bengali, is a species of climbing gourami native to Bangladesh and India, where it occurs in many types of standing water bodies. This species reaches a total length of 30 cm (12 in) and is carnivorous, feeding on water invertebrates and their larvae.
Several koi swim around in a pond in Japan. (video) A school of koi containing multiple different varieties Koi (鯉, Japanese:, literally "carp"), or more specifically nishikigoi (錦鯉, Japanese: [ɲiɕi̥kiꜜɡoi], literally "brocaded carp"), are colored varieties of carp (Cyprinus sp.) that are kept for decorative purposes in outdoor koi ponds or water gardens.
