  2. Cartesian genetic programming - Wikipedia

    en.wikipedia.org/wiki/Cartesian_genetic_programming

    It grew from a method of evolving digital circuits developed by Julian F. Miller and Peter Thomson in 1997. [1] The term ‘Cartesian genetic programming’ first appeared in 1999 [2] and was proposed as a general form of genetic programming in 2000. [3] It is called ‘Cartesian’ because it represents a program using a two-dimensional grid ...

  3. Orthogonal coordinates - Wikipedia

    en.wikipedia.org/wiki/Orthogonal_coordinates

    A conformal map acting on a rectangular grid. Note that the orthogonality of the curved grid is retained. While vector operations and physical laws are normally easiest to derive in Cartesian coordinates, non-Cartesian orthogonal coordinates are often used instead for the solution of various problems, especially boundary value problems, such as those arising in field theories of quantum ...

  4. Rotation of axes in two dimensions - Wikipedia

    en.wikipedia.org/wiki/Rotation_of_axes_in_two...

    A point P has coordinates (x, y) with respect to the original system and coordinates (x′, y′) with respect to the new system. [1] In the new coordinate system, the point P will appear to have been rotated in the opposite direction, that is, clockwise through the angle . A rotation of axes in more than two dimensions is defined similarly. [2 ...

  5. European Terrestrial Reference System 1989 - Wikipedia

    en.wikipedia.org/wiki/European_Terrestrial...

    The European Terrestrial Reference System 1989 (ETRS89) is an ECEF (Earth-Centered, Earth-Fixed) geodetic Cartesian reference frame, in which the Eurasian Plate as a whole is static. The coordinates and maps in Europe based on ETRS89 are not subject to change due to the continental drift .

  6. ModelCenter - Wikipedia

    en.wikipedia.org/wiki/ModelCenter

    RSM Toolkit 3.0 gives users a mathematical model based on source data from simulations or actual experiments. This new model can then be integrated as a component within another model within ModelCenter. QuickWrap 3.0 automates batch mode programs. The Enhanced Workflow Module allows workflows to be graphically constructed and executed.

  7. Cartesianism - Wikipedia

    en.wikipedia.org/wiki/Cartesianism

    Cartesianism is the philosophical and scientific system of René Descartes and its subsequent development by other seventeenth century thinkers, most notably François Poullain de la Barre, Nicolas Malebranche and Baruch Spinoza. [1] Descartes is often regarded as the first thinker to emphasize the use of reason to develop the natural sciences. [2]

  8. Table of spherical harmonics - Wikipedia

    en.wikipedia.org/wiki/Table_of_spherical_harmonics

    Some of these formulas are expressed in terms of the Cartesian expansion of the spherical harmonics into polynomials in x, y, z, and r. For purposes of this table, it is useful to express the usual spherical to Cartesian transformations that relate these Cartesian components to θ {\displaystyle \theta } and φ {\displaystyle \varphi } as

  9. Configuration space (physics) - Wikipedia

    en.wikipedia.org/wiki/Configuration_space_(physics)

    The set of coordinates that define the position of a reference point and the orientation of a coordinate frame attached to a rigid body in three-dimensional space form its configuration space, often denoted () where represents the coordinates of the origin of the frame attached to the body, and () represents the rotation matrices that define the orientation of this frame relative to a ground ...
