  2. Split graph - Wikipedia

    en.wikipedia.org/wiki/Split_graph

    In this case, G has a unique partition (C, i) into a clique and an independent set, C is the maximum clique, and i is the maximum independent set. Some other optimization problems that are NP-complete on more general graph families, including graph coloring , are similarly straightforward on split graphs.

  3. Adjacency matrix - Wikipedia

    en.wikipedia.org/wiki/Adjacency_matrix

    Using the first definition, the in-degrees of a vertex can be computed by summing the entries of the corresponding column and the out-degree of vertex by summing the entries of the corresponding row. When using the second definition, the in-degree of a vertex is given by the corresponding row sum and the out-degree is given by the corresponding ...

  4. Block matrix - Wikipedia

    en.wikipedia.org/wiki/Block_matrix

    In mathematics, a block matrix or a partitioned matrix is a matrix that is interpreted as having been broken into sections called blocks or submatrices. [1] [2]Intuitively, a matrix interpreted as a block matrix can be visualized as the original matrix with a collection of horizontal and vertical lines, which break it up, or partition it, into a collection of smaller matrices.

  5. Data parallelism - Wikipedia

    en.wikipedia.org/wiki/Data_parallelism

    For multiplication, we can divide matrix A and B into blocks along rows and columns respectively. This allows us to calculate every element in matrix C individually thereby making the task parallel. For example: A[m x n] dot B [n x k] can be finished in O ( n ) {\displaystyle O(n)} instead of O ( m ∗ n ∗ k ) {\displaystyle O(m*n*k)} when ...

    Take Pascal's triangle, which is a triangular array of numbers in which those at the ends of the rows are 1 and each of the other numbers is the sum of the nearest two numbers in the row just above it (the apex, 1, being at the top). The following is an APL one-liner function to visually depict Pascal's triangle:

    The man confessed that he knew better than to leave a dirty cup in a common area, but it had slipped his mind. He said he regretted having lied about it when caught. Hamm went in for the kill. He turned to the whiteboard where another addict was recording all the group’s concerns, listing the proposed punishments in increasingly crowded columns.
