  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. Pattern search (optimization) - Wikipedia

    en.wikipedia.org/wiki/Pattern_search_(optimization)

    Example of convergence of a direct search method on the Broyden function. At each iteration, the pattern either moves to the point which best minimizes its objective function, or shrinks in size if no point is better than the current point, until the desired accuracy has been achieved, or the algorithm reaches a predetermined number of iterations.

  4. 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?

  5. Software design pattern - Wikipedia

    en.wikipedia.org/wiki/Software_design_pattern

    In software engineering, a software design pattern or design pattern is a general, reusable solution to a commonly occurring problem in many contexts in software design. [1] A design pattern is not a rigid structure to be transplanted directly into source code.

  6. 3D projection - Wikipedia

    en.wikipedia.org/wiki/3D_projection

    The standing point (P.S.) is located on the ground plane π, and the point of view (P.V.) is right above it. P.P. is its projection on the picture plane α. L.O. and L.T. are the horizon and the ground lines (linea d'orizzonte and linea di terra). The bold lines s and q lie on π, and intercept α at Ts and Tq respectively.

  7. GRASP (object-oriented design) - Wikipedia

    en.wikipedia.org/wiki/GRASP_(object-oriented_design)

    The indirection pattern supports low coupling and reuses potential between two elements by assigning the responsibility of mediation between them to an intermediate object. An example of this is the introduction of a controller component for mediation between data (model) and its representation (view) in the model-view-controller pattern.

  8. Model–view–presenter - Wikipedia

    en.wikipedia.org/wiki/Model–view–presenter

    Diagram that depicts the model–view–presenter (MVP) GUI design pattern. Model–view–presenter (MVP) is a derivation of the model–view–controller (MVC) architectural pattern, and is used mostly for building user interfaces. In MVP, the presenter assumes the functionality of the "middle-man". In MVP, all presentation logic is pushed to ...

  9. Vantage-point tree - Wikipedia

    en.wikipedia.org/wiki/Vantage-point_tree

    The way a vantage-point tree stores data can be represented by a circle. [6] First, understand that each node of this tree contains an input point and a radius. All the left children of a given node are the points inside the circle and all the right children of a given node are outside of the circle.
