WebIn order to determine if the model is infeasible or unbounded, you should set the DualReductions parameter to 0, call reset on the model, and optimize once again. The optimization status that is returned should be either INFEASIBLE or UNBOUNDED. WebJun 10, 2024 · These problems are even NP-complete, which usually means that solving large instances becomes infeasible. But CVXPY tries its best anyway. As a final note, there are more interesting linear programs than the one we covered, of course. For example, check out the Stigler diet which is a similar problem, but with much more food and …

Enable here WebCVXPY represents mixed-integer cone programs as (Aff) min { c.T @ x A @ x + b in K, x [bools] in {0, 1}, x [ints] in Z } + d. Some solvers do not accept input in the form (Aff). A general pattern we find across solver types is that the feasible set is represented by (Dir) min { f @ y G @ y <=_ {K_aff} h, y in K_dir
