This algorithm can easily be adapted to compute the variance of a finite population: simply divide by n instead of n − 1 on the last line.. Because SumSq and (Sum×Sum)/n can be very similar numbers, cancellation can lead to the precision of the result to be much less than the inherent precision of the floating-point arithmetic used to perform the computation.
Hasse diagram of some classes of quantitative automata, ordered by expressiveness. [1]: Fig.1 In theoretical computer science and formal language theory, a weighted automaton or weighted finite-state machine is a generalization of a finite-state machine in which the edges have weights, for example real numbers or integers.

Integer addition, for example, can be performed as a single machine instruction, and some offer specific instructions to process sequences of characters with a single instruction. [7] But the choice of primitive data type may affect performance, for example it is faster using SIMD operations and data types to operate on an array of floats.
NumPy (pronounced / ˈ n ʌ m p aɪ / NUM-py) is a library for the Python programming language, adding support for large, multi-dimensional arrays and matrices, along with a large collection of high-level mathematical functions to operate on these arrays. [3]
With the help of the weighted sum, the total Pareto front can be obtained by a suitable choice of weights, provided that it is convex. [20] This is illustrated by the adjacent picture on the left. The point P {\displaystyle {\mathsf {P}}} on the green Pareto front is reached by the weights w 1 {\displaystyle w_{1}} and w 2 {\displaystyle w_{2 ...
From hero to zero. Ten years ago, Russell Wilson was the talk of the NFL. He had led the Seahawks to a dominant victory at Super Bowl 48, the franchise’s first ever title, in just his second ...
Let j in R be the index of max(w R) in w. Add j to P. Remove j from R. Let A P be A restricted to the variables included in P. Let s be vector of same length as x. Let s P denote the sub-vector with indexes from P, and let s R denote the sub-vector with indexes from R. Set s P = ((A P) T A P) −1 (A P) T y; Set s R to zero; While min(s P) ≤ 0:
