Cvxpy warning
WebApr 4, 2024 · First, try increasing the number of iterations ( iter.max) or playing with other settings in coxph.control (). It's possible that convergence is just unusually slow or you are bouncing back and forth among some solutions that are pretty close but don't quite meet the eps parameter requirement to stop the iteration. WebJan 16, 2024 · Most advanced solvers support this type of variable directly. As CVXPY does not understand semi-continuous variables, we can use binary variables δ ∈ {0,1} and form the constraints: δ⋅min ≤ w ≤ δ⋅max. where we can set max=1. This makes the problem a MIQP (Mixed-Integer Quadratic Programming) problem. This usually means that you ...
