Unfortunately, it only works on 32-bit versions of MATLAB. I believe MATLAB R2015b and R2010a were the last versions available on Windows and Mac, respectively. If you have access to...

No problem. Could you please send me the following (via direct e-mail to my Cornell address) and I’ll provide you a download link. As part of the licensing terms for...

Great news ... I'm happy to contribute where I can, but there was no way I was going to be an adequate maintainer.

I agree that this should not happen. If there are no overloads, then the lack of convergence is not due to infeasibility, but probably some numerical issue with that particular...

Is the case one you can share? If so, feel free to send it to me directly if you don't want to post it here.

Could you try the following with your result ... ``` sum([DCopf.softlims.PMAX.ovl_cost; DCopf.softlims.PMIN.ovl_cost; DCopf.softlims.RATE_Aovl_cost]) ``` ... just to double-check that it also returns 0. If it does, then maybe you could...

Using the standard `runopf()` to check for feasibility is probably not the ideal, since it will fail to converge if infeasible, but there is still no guarantee that infeasibility was...

Yes, both AC and DC OPF are subject to the same issue when line outages create islands. In order to solve the islanded system, even with soft-constraints, you will need...

If the OPF converged, you can ignore the warnings. If not, then you may need to try a different solver like IPOPT, which is probably a bit more robust than...

If you have a MATPOWER case of the topology of interest, you can use [`find_islands()`](https://github.com/MATPOWER/matpower/blob/master/lib/find_islands.m) or [`case_info()`](https://github.com/MATPOWER/matpower/blob/master/lib/case_info.m) to find the isolated buses. There is also an [`extract_islands()`](https://github.com/MATPOWER/matpower/blob/master/lib/extract_islands.m), in case you...
