The pivot or pivot element is the element of a matrix, or an array, which is selected first by an algorithm (e.g. Gaussian elimination, simplex algorithm...

Quicksort is a divide-and-conquer algorithm. It works by selecting a "pivot" element from the array and partitioning the other elements into two sub-arrays...

implemented as a pivot operation. First, a nonzero pivot element is selected in a nonbasic column. The row containing this element is multiplied by its...

Look up pivot, pivoting, or pivots in Wiktionary, the free dictionary. Pivot may refer to: Pivot, the point of rotation in a lever system More generally...

For example, we might swap rows to perform partial pivoting, or we might do it to set the pivot element a n , n {\displaystyle a_{n,n}} on the main diagonal...

used to supply a good pivot for an exact selection algorithm, most commonly quickselect, that selects the kth smallest element of an initially unsorted...

selection are based on choosing a special "pivot" element from the input, and using comparisons with this element to divide the remaining n − 1 {\displaystyle...

choosing one element as a pivot and partitioning the data in two based on the pivot, accordingly as less than or greater than the pivot. However, instead...

last element as pivot) this occurs for sorted data, which is a common case. The most complex issue in quicksort is thus choosing a good pivot element, as...

optimize this effect, Sij should be the off-diagonal element with the largest absolute value, called the pivot. The Jacobi eigenvalue method repeatedly performs...

involving a "pivot vertex" u, chosen from P (or more generally, as later investigators realized, from P ⋃ X). Then, neighbors of that pivot element are not...

computational method for Kalman decomposition, which is based on the pivot element method. A variant of Rosenbrock’s method is implemented in the minreal...

var int axis := depth mod k; // Sort point list and choose median as pivot element select median by axis from pointList; // Create node and construct subtree...

identifies a pivot element in the list and then partitions the list into two sublists, those elements less than the pivot and those greater than the pivot. Spreadsort...

computing the transpose of a matrix without using much additional storage Pivot element — entry in a matrix on which the algorithm concentrates Matrix-free...

Consider an algorithm to find the kth element of an array. A deterministic approach would be to choose a pivot element near the median of the list and partition...

partition step is massively parallel (each input element should be compared to a chosen pivot element) and the two recursive calls can be performed in...

is partitioned. The simplest pivot selection algorithm is to take the first or the last element of the list as the pivot, causing poor behavior for the...

cavity during a single visit. It often includes a protective element called a ferrule. Pivot teeth were developed to shorten the execution cycle and skip...
