http://web.cvxr.com/cvx/beta/doc/solver.html WebYou can use CVXPY to find the optimal dual variables for a problem. When you call prob.solve () each dual variable in the solution is stored in the dual_value field of the constraint it corresponds to. from cvxpy import * # Create two scalar optimization variables. x = Variable() y = Variable() # Create two constraints. constraints = [x + y ...

WebMean-Variance Optimization. Mathematical optimization is a very difficult problem in general, particularly when we are dealing with complex objectives and constraints. However, convex optimization problems are a well-understood class of problems, which happen to be incredibly useful for finance. A convex problem has the following form: minimise ... WebThe function ECOS_csolve is a wrapper around the ecos csolve C function. Conic constraints are specified using the \(G\) and \(h\) parameters and can be NULL and zero length vector respectively indicating an absence of conic constraints. Similarly, equality constraints are specified via \(A\) and \(b\) parameters with NULL and empty vector values representing …
