2. Stars and bars (combinatorics) - Wikipedia

   en.wikipedia.org/wiki/Stars_and_bars_(combinatorics)

   Stars and bars (combinatorics) In the context of combinatorial mathematics, stars and bars (also called "sticks and stones", [ 1 ] "balls and bars", [ 2 ] and "dots and dividers" [ 3 ]) is a graphical aid for deriving certain combinatorial theorems. It can be used to solve many simple counting problems, such as how many ways there are to put n ...

3. Star (game theory) - Wikipedia

   en.wikipedia.org/wiki/Star_(game_theory)

   Star (game theory) In combinatorial game theory, star, written as ∗ or ∗1, is the value given to the game where both players have only the option of moving to the zero game. Star may also be denoted as the surreal form {0|0}. This game is an unconditional first-player win. Star, as defined by John Conway in Winning Ways for your ...

4. Star schema - Wikipedia

   en.wikipedia.org/wiki/Star_schema

   Star schema. In computing, the star schema or star model is the simplest style of data mart schema and is the approach most widely used to develop data warehouses and dimensional data marts. [1] The star schema consists of one or more fact tables referencing any number of dimension tables. The star schema is an important special case of the ...

5. Conway's Game of Life - Wikipedia

   en.wikipedia.org/wiki/Conway's_Game_of_Life

   The Game of Life, also known simply as Conway's Game of Life or simply Life, is a cellular automaton devised by the British mathematician John Horton Conway in 1970. [1] It is a zero-player game, [2][3] meaning that its evolution is determined by its initial state, requiring no further input. One interacts with the Game of Life by creating an ...

6. Radar chart - Wikipedia

   en.wikipedia.org/wiki/Radar_chart

   This spider chart represents the allocated budget versus actual spending for a given organization. A radar chart is a graphical method of displaying multivariate data in the form of a two-dimensional chart of three or more quantitative variables represented on axes starting from the same point. The relative position and angle of the axes is ...

7. Star (graph theory) - Wikipedia

   en.wikipedia.org/wiki/Star_(graph_theory)

   In graph theory, a star Sk is the complete bipartite graph K1,k : a tree with one internal node and k leaves (but no internal nodes and k + 1 leaves when k ≤ 1). Alternatively, some authors define Sk to be the tree of order k with maximum diameter 2; in which case a star of k > 2 has k − 1 leaves. A star with 3 edges is called a claw.

8. Star domain - Wikipedia

   en.wikipedia.org/wiki/Star_domain

   A star domain (equivalently, a star-convex or star-shaped set) is not necessarily convex in the ordinary sense. An annulus is not a star domain.. In geometry, a set in the Euclidean space is called a star domain (or star-convex set, star-shaped set [1] or radially convex set) if there exists an such that for all , the line segment from to lies in .

9. A* search algorithm - Wikipedia

   en.wikipedia.org/wiki/A*_search_algorithm

   A* search algorithm. A* (pronounced "A-star") is a graph traversal and pathfinding algorithm, which is used in many fields of computer science due to its completeness, optimality, and optimal efficiency. [1] Given a weighted graph, a source node and a goal node, the algorithm finds the shortest path (with respect to the given weights) from ...
