  2. Vertical line test - Wikipedia

    en.wikipedia.org/wiki/Vertical_line_test

    The vertical line test, shown graphically. The abscissa shows the domain of the (to be tested) function. In mathematics, the vertical line test is a visual way to determine if a curve is a graph of a function or not. A function can only have one output, y, for each unique input, x.

  3. Depth-first search - Wikipedia

    en.wikipedia.org/wiki/Depth-first_search

    it delays checking whether a vertex has been discovered until the vertex is popped from the stack rather than making this check before adding the vertex. If G is a tree, replacing the queue of the breadth-first search algorithm with a stack will yield a depth-first search algorithm. For general graphs, replacing the stack of the iterative depth ...

  4. Cycle detection - Wikipedia

    en.wikipedia.org/wiki/Cycle_detection

    For example, assume the function values are 32-bit integers, so + and +. Then Gosper's algorithm will find the cycle after less than μ + 2 λ {\displaystyle \mu +2\lambda } function evaluations (in fact, the most possible is 3 ⋅ 2 31 − 1 {\displaystyle 3\cdot 2^{31}-1} ), while consuming the space of 33 values (each value being a 32-bit ...

  5. Line graph - Wikipedia

    en.wikipedia.org/wiki/Line_graph

    In the mathematical discipline of graph theory, the line graph of an undirected graph G is another graph L(G) that represents the adjacencies between edges of G. L(G) is constructed in the following way: for each edge in G, make a vertex in L(G); for every two edges in G that have a vertex in common, make an edge between their corresponding vertices in L(G).

  6. Hierarchical clustering - Wikipedia

    en.wikipedia.org/wiki/Hierarchical_clustering

    The probability that candidate clusters spawn from the same distribution function (V-linkage). The product of in-degree and out-degree on a k-nearest-neighbour graph (graph degree linkage). [14] The increment of some cluster descriptor (i.e., a quantity defined for measuring the quality of a cluster) after merging two clusters. [15] [16] [17]

  7. SAS (software) - Wikipedia

    en.wikipedia.org/wiki/SAS_(software)

    SAS provides a graphical point-and-click user interface for non-technical users and more through the SAS language. [3] SAS programs have DATA steps, which retrieve and manipulate data, PROC (procedures) which analyze the data, and may also have functions. [4] Each step consists of a series of statements. [5]

  9. Network motif - Wikipedia

    en.wikipedia.org/wiki/Network_motif

    A graph is called recurrent (or frequent) in G when its frequency F G (G′) is above a predefined threshold or cut-off value. We use terms pattern and frequent sub-graph in this review interchangeably. There is an ensemble Ω(G) of random graphs corresponding to the null-model associated to G.
