  2. Functional database model - Wikipedia

    en.wikipedia.org/wiki/Functional_Database_Model

    Cells may also be empty and deemed to have a zero value for purposes of consolidation. As with spreadsheets, users need not worry about executing recalculation. When the value of a cell is requested, the value that is returned is up to date with respect to the values of all of the cells that go into its calculation i.e. the cells on which it ...

  3. Spreadsheet - Wikipedia

    en.wikipedia.org/wiki/Spreadsheet

    When the computer calculates a formula in one cell to update the displayed value of that cell, cell reference(s) in that cell, naming some other cell(s), causes the computer to fetch the value of the named cell(s). A cell on the same "sheet" is usually addressed as: =A1 A cell on a different sheet of the same spreadsheet is usually addressed as:

  4. Linked list - Wikipedia

    en.wikipedia.org/wiki/Linked_list

    An unrolled linked list is a linked list in which each node contains an array of data values. This leads to improved cache performance, since more list elements are contiguous in memory, and reduced memory overhead, because less metadata needs to be stored for each element of the list.

  5. Essbase - Wikipedia

    en.wikipedia.org/wiki/Essbase

    If the multidimensional database reserved storage space for every possible value, it would need to store 2,400,000,000 (4 × 4 × 3 × 10,000 × 5,000) cells. If the software maps each cell as a 64-bit floating point value, this equates to a memory requirement of about 17.9 GiB (exactly 19.2 GB ).

  6. Dynamic programming - Wikipedia

    en.wikipedia.org/wiki/Dynamic_programming

    The partial alignments can be tabulated in a matrix, where cell (i,j) contains the cost of the optimal alignment of A[1..i] to B[1..j]. The cost in cell (i,j) can be calculated by adding the cost of the relevant operations to the cost of its neighboring cells, and selecting the optimum.

  7. Adaptive mesh refinement - Wikipedia

    en.wikipedia.org/wiki/Adaptive_mesh_refinement

    Adaptive mesh refinement provides such a dynamic programming environment for adapting the precision of the numerical computation based on the requirements of a computation problem in specific areas of multi-dimensional graphs which need precision while leaving the other regions of the multi-dimensional graphs at lower levels of precision and ...

  8. Linear probing - Wikipedia

    en.wikipedia.org/wiki/Linear_probing

    To search for a given key x, the cells of T are examined, beginning with the cell at index h(x) (where h is the hash function) and continuing to the adjacent cells h(x) + 1, h(x) + 2, ..., until finding either an empty cell or a cell whose stored key is x. If a cell containing the key is found, the search returns the value from that cell.

  9. V-optimal histograms - Wikipedia

    en.wikipedia.org/wiki/V-optimal_histograms

    A v-optimal histogram is based on the concept of minimizing a quantity which is called the weighted variance in this context. [1] This is defined as = =, where the histogram consists of J bins or buckets, n j is the number of items contained in the jth bin and where V j is the variance between the values associated with the items in the jth bin.
