Dispersive flies optimisation (DFO) is a bare-bones swarm intelligence algorithm which is inspired by the swarming behaviour of flies hovering over food sources. [1] DFO is a simple optimiser which works by iteratively trying to improve a candidate solution with regard to a numerical measure that is calculated by a fitness function .
The genus Pseudacteon, or ant-decapitating flies, of which 110 species have been documented, is a parasitoid of ants. Pseudacteon species reproduce by laying eggs in the thorax of the ant. The first instar larvae migrate to the head, where they feed on the ant's hemolymph , muscle and nerve tissue.
The Ceratopogonidae (biting midges) include serious blood-sucking pests, feeding both on humans and other mammals. Some of them spread the livestock diseases known as blue tongue and African horse sickness – other species though, are at least partly nectar feeders, and some even suck insect bodily fluids.
In pseudocode the algorithm can be stated as: Begin 1) Objective function: (), = (,,...,); 2) Generate an initial population of fireflies (=,, …,);. 3) Formulate light intensity I so that it is associated with () (for example, for maximization problems, () or simply = ();) 4) Define absorption coefficient γ while (t < MaxGeneration) for i = 1 : n (all n fireflies) for j = 1 : i (n fireflies ...
For example, the flies known as "emergers" in North America are designed by fly fishermen to resemble subimago mayflies, and are intended to lure freshwater trout. [83] In 1983, Patrick McCafferty recorded that artificial flies had been based on 36 genera of North American mayfly, from a total of 63 western species and 103 eastern/central species.
The room is a reflection of Kusama's hallucinations that she had had since she was a child. The installation, which is mostly made up of LED lights and mirrors, allows the viewer to "obliterate" themselves and unite themselves with the room.
The NFL on Fox's Super Bowl pregame had a bizarre tribute segment for Jimmy Johnson without any context. Is the Hall of Fame coach retiring?
At any given time, the number of females at a swarm site consists of both those swarming and those resting. The total number of females at a swarm site then includes both the swarming and resting female flies. [4] Swarms generally range from 0.5 to 1.5 m in diameter, with the swarms being 0.5 to 6 m above the ground. [4]
