python - Violated constraint in CVXPY - Stack Overflow

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 http://cvxr.com/cvx/doc/solver.html WebDetects infeasibility: Robustly and reliably detects infeasible problems.

WebNov 1, 2024 · 1 This my first time trying to use cvxpy. I have 2 very simple constrains: x = cp.Variable ( (5, 5)) constrains = [cp.sum (x) == 1.0, 0 <= x] The solution worked most of time, satisfying both constrains. But sometimes the solution only satisfied the first constrain and spit out negative values. WebJan 27, 2024 · OS: Archlinux (from pypi) on python 3.7. CVXPY Version: '1.1.7'. mosek version: '9.2.21'.

WebJan 1, 2010 · CVXPY provides an API where certain solvers can differentiate the map from the parameters of an optimization problem to the optimal solution of that problem. The differentiation abilities are currently only available when SCS is used as the solver. WebMar 14, 2024 · As a constraint, where x,y and z are cvxpy variables. The solution is to add the constraint. (1-x) * large_num > z - y. Where large_num is far larger than z and y. The way it works is that. if x is false (0), then we get "large_num > z-y", which is always true, so the constraint is redundant. if x is true (1), then we get 0 > z-y which is ...
