The pivot algorithm works by taking a self-avoiding walk and randomly choosing a point on this walk, and then applying symmetrical transformations (rotations and reflections) on the walk after the n th step to create a new walk. Calculating the number of self-avoiding walks in any given lattice is a common computational problem. There is ...
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, etc.), to do certain calculations. In the case of matrix algorithms, a pivot entry is usually required to be at least distinct from zero, and often distant from it; in this case finding this ...
The Viola–Jones object detection framework is a machine learning object detection framework proposed in 2001 by Paul Viola and Michael Jones. [1] [2] It was motivated primarily by the problem of face detection, although it can be adapted to the detection of other object classes.
Gait recognition is a type of behavioral biometric authentication that recognizes and verifies people by their walking style and pace. [25] [26] Advances in gait recognition have led to the development of techniques for forensics use since each person can have a gait defined by unique measurements such as the locations of ankle, knee, and hip.

The algorithm generates a random permutations uniformly so long as the hardware operates in a fair manner. In 2015, Bacher et al. produced MERGESHUFFLE, an algorithm that divides the array into blocks of roughly equal size, uses Fisher—Yates to shuffle each block, and then uses a random merge recursively to give the shuffled array.

Pivot foot – The foot that must remain touching the floor to avoid traveling Run – An interval in which one team heavily outscores the other. Hot hand fallacy – Is the notion that a streak of positive successes are likely to continue, but statistics show that the probability of a streak continuing actually goes down as the length increases.
