Originally thought to be a skill possessed only by humans, some tool use requires a ...
Fixed action patterns are said to be produced by the innate releasing mechanism, a "hard-wired" neural network, in response to a sign/key stimulus or releaser. [1][2] Once released, a fixed action pattern runs to completion. [1] This term is often associated with Konrad Lorenz, who is the founder of the concept. [1]
Boids. Boids is an artificial life program, developed by Craig Reynolds in 1986, which simulates the flocking behaviour of birds, and related group motion. His paper on this topic was published in 1987 in the proceedings of the ACM SIGGRAPH conference. [1] The name "boid" corresponds to a shortened version of "bird-oid object", which refers to ...

Ikejime (活け締め) or ikijime (活き締め) is a method of killing fish that maintains the quality of its meat. [1] The technique originated in Japan, but is now in widespread use. It involves the insertion of a spike quickly and directly into the hindbrain, usually located slightly behind and above the eye, thereby causing immediate brain ...
Parity benchmark. v. t. e. In computational science, particle swarm optimization (PSO) [ 1 ] is a computational method that optimizes a problem by iteratively trying to improve a candidate solution with regard to a given measure of quality. It solves a problem by having a population of candidate solutions, here dubbed particles, and moving ...
Felidae (/ ˈfɛlɪdiː /) is the family of mammals in the order Carnivora colloquially referred to as cats. A member of this family is also called a felid (/ ˈfiːlɪd /). [3][4][5][6] The 41 extant Felidae species exhibit the greatest diversity in fur patterns of all terrestrial carnivores. [7] Cats have retractile claws, slender muscular ...
