WebFeb 6, 2024 · The only way around this that I know if is to use cvx_solver-settings to set maximum number of iterations for the solver. Run CVX with max iterations set to 1 and record the “final” output: Then re-run CVX with max iterations set to 2, record that final output, etc. Of course, CVX was not designed with the intention of supporting “circus ...
