  2. Diamond-square algorithm - Wikipedia

    en.wikipedia.org/wiki/Diamond-square_algorithm

    The square step: For each diamond in the array, set the midpoint of that diamond to be the average of the four corner points plus a random value. Each random value is multiplied by a scale constant, which decreases with each iteration by a factor of 2 −h , where h is a value between 0.0 and 1.0 (lower values produce rougher terrain).

  3. Multiple inheritance - Wikipedia

    en.wikipedia.org/wiki/Multiple_inheritance

    The "diamond problem" (sometimes referred to as the "Deadly Diamond of Death" [6]) is an ambiguity that arises when two classes B and C inherit from A, and class D inherits from both B and C. If there is a method in A that B and C have overridden , and D does not override it, then which version of the method does D inherit: that of B, or that of C?

  4. Diamond graph - Wikipedia

    en.wikipedia.org/wiki/Diamond_graph

    The triangle-free graphs are diamond-free graphs, since every diamond contains a triangle. The diamond-free graphs are locally clustered: that is, they are the graphs in which every neighborhood is a cluster graph. Alternatively, a graph is diamond-free if and only if every pair of maximal cliques in the graph shares at most one vertex.

  5. Trait (computer programming) - Wikipedia

    en.wikipedia.org/wiki/Trait_(computer_programming)

    Python: Via a third-party library, [34] [35] or via higher-order mixin classes [36] Racket: Supports traits as a library and uses macros, structures, and first-class classes to implement them. [37] Ruby: Module mixins can be used to implement traits. [38] Rust [39] Scala [40] [41] trait is builtin supported with the key word trait.

  6. Local binary patterns - Wikipedia

    en.wikipedia.org/wiki/Local_binary_patterns

    Local binary patterns (LBP) is a type of visual descriptor used for classification in computer vision. LBP is the particular case of the Texture Spectrum model proposed in 1990. LBP is the particular case of the Texture Spectrum model proposed in 1990.

  7. Common spatial pattern - Wikipedia

    en.wikipedia.org/wiki/Common_spatial_pattern

    Common spatial pattern (CSP) is a mathematical procedure used in signal processing for separating a multivariate signal into additive subcomponents which have maximum differences in variance between two windows.

  8. Hermann–Mauguin notation - Wikipedia

    en.wikipedia.org/wiki/Hermann–Mauguin_notation

    The d glide is often called the diamond glide plane as it features in the diamond structure. In cases where there are two possibilities among a, b, and c (such as a or b), the letter e is used. (In these cases, centering entails that both glides occur.) To summarize: a, b, or c glide translation along half the lattice vector of this face.

  9. Eye pattern - Wikipedia

    en.wikipedia.org/wiki/Eye_pattern

    In telecommunications, an eye pattern, also known as an eye diagram, is an oscilloscope display in which a digital signal from a receiver is repetitively sampled and applied to the vertical input (y-axis), while the data rate is used to trigger the horizontal sweep (x-axis). It is so called because, for several types of coding, the pattern ...
