Web11 Nov 2013 · This is obvious for equality constraints, but we even allow a tolerance on inequality constraints: inequality constraints are often active at an optimal solution, "exact" equality is generally impossible to achieve, and it would require special logic (often not part of the original algorithm) to ensure that the inequality constraint is strictly respected. Web11 Apr 2024 · Least squares (scipy.linalg.lstsq) is guaranteed to converge.In fact, there is a closed form analytical solution (given by (A^T A)^-1 A^Tb (where ^T is matrix transpose and ^-1 is matrix inversion). The standard optimization problem, however, is not generally solvable – we are not guaranteed to find a minimizing value. to shed feathers
