  2. Bird (mathematical artwork) - Wikipedia

    en.wikipedia.org/wiki/Bird_(mathematical_artwork)

    The 500 line segments defined above together form a shape in the Cartesian plane that resembles a bird with open wings. Looking at the line segments on the wings of the bird causes an optical illusion and may trick the viewer into thinking that the segments are curved lines. Therefore, the shape can also be considered as an optical artwork.

    Hamid Naderi Yeganeh (Persian: حمید نادری یگانه; born 26 July 1990, in Iran [1]) is an Iranian mathematical artist and digital artist. [2] [3] [4] He is known for using mathematical formulas to create drawings of real-life objects, intricate and symmetrical illustrations, animations, fractals and tessellations.

  4. Plotting algorithms for the Mandelbrot set - Wikipedia

    en.wikipedia.org/wiki/Plotting_algorithms_for...

    As with border tracing, rectangle checking only works on areas with one discrete color. But even if the outer area uses smooth/continuous coloring then rectangle checking will still speed up the costly inner area of the Mandelbrot set. Unless the inner area also uses some smooth coloring method, for instance interior distance estimation.

  5. Orbit trap - Wikipedia

    en.wikipedia.org/wiki/Orbit_trap

    In mathematics, an orbit trap is a method of colouring fractal images based upon how close an iterative function, used to create the fractal, approaches a geometric shape, called a "trap". Typical traps are points, lines, circles, flower shapes and even raster images. Orbit traps are typically used to colour two dimensional fractals ...

  6. Coloring - Wikipedia

    Coloring or colouring may refer to: Color, or the act of changing the color of an object Coloring, the act of adding color to the pages of a coloring book; Coloring, the act of adding color to comic book pages, where the person's job title is Colorist; Graph coloring, in mathematics; Hair coloring; Food coloring; Hand-colouring of photographs ...

  7. List coloring - Wikipedia

    en.wikipedia.org/wiki/List_coloring

    Given a graph G and given a set L(v) of colors for each vertex v (called a list), a list coloring is a choice function that maps every vertex v to a color in the list L(v). As with graph coloring, a list coloring is generally assumed to be proper , meaning no two adjacent vertices receive the same color.

  8. Animal migration - Wikipedia

    en.wikipedia.org/wiki/Animal_migration

    Bird migration is controlled primarily by day length, signalled by hormonal changes in the bird's body. [19] On migration, birds navigate using multiple senses. Many birds use a sun compass, requiring them to compensate for the sun's changing position with time of day. [20] Navigation involves the ability to detect magnetic fields. [21]

  9. Greedy coloring - Wikipedia

    en.wikipedia.org/wiki/Greedy_coloring

    In the study of graph coloring problems in mathematics and computer science, a greedy coloring or sequential coloring [1] is a coloring of the vertices of a graph formed by a greedy algorithm that considers the vertices of the graph in sequence and assigns each vertex its first available color. Greedy colorings can be found in linear time, but ...
