Cvxpy tracking error

WebCVXPY is an open source Python-embedded modeling language for convex optimization problems. It lets you express your problem in a natural way that follows the math, rather than in the restrictive standard form required by solvers. For example, the following code solves a least-squares problem with box constraints: WebApr 27, 2024 · to cvxpy Hi Sandeep, In addition to Michal's comment above, the constraints, $\ X_i - X_j^P\ _2 \geq D" is not convex constraints, hence cvxpy wouldn't accept it.
