status = 5?

[victor.chubukov]

Hi,

I'm using knitro in a C program using reverse communication mode. It
seems to finish with the problem, but then returns a status code of 5,
which is not listed as a possible return value in the documentation.
Can someone suggest what's going on?

Thanks.

Hi Victor,

Return code 5 is "FINISHED". I guess it's not in the User Manual,
but it is in the knitro.h header file. Not sure why you are getting
it. One possibility is that KNITRO completed, giving you a normal
status, and then you called KTR_solve() again (unnecessarily); in this
case KNITRO returns "FINISHED" because there is nothing for it to do.

Thanks, that's exactly what I realized also. I was migrating from
version 4.x and using KTR_solve to solve the same problem repeatedly
(with different objective functions). I didn't notice that I had to
call KTR_restart (obviously makes sense that I would have to reset
internal state).
