In mathematical optimization, the problem of non-negative least squares (NNLS) is a type of constrained least squares problem where the coefficients are not allowed to become negative. That is, given a matrix A and a (column) vector of response variables y, the goal is to find subject to x ≥ 0. Here x ≥ 0 means that each component of the vector x should be non-negative, and ‖·‖2 denotes the Euclidean norm. Non-negative least squares problems turn up as subproblems in matrix decomposition, e.g. in algorithms for PARAFAC and non-negative matrix/tensor factorization. The latter can be considered a generalization of NNLS. Another generalization of NNLS is bounded-variable least squares (BVLS), with simultaneous upper and lower bounds αi ≤ xi ≤ βi. (Wikipedia).

Proof for Square Root of Convergent Sequence | Real Analysis Exercises
We prove if a sequence of nonnegative numbers converges to a limit, then the square root of that sequence converges to the square root of that limit, which we could call the square root limit law or limit law for square roots. #RealAnalysis Put more precisely, if every x_n is at least 0,
