I figured out a workaround for this issue. Line 270 of auglag/auglag.c reads:
if (nlopt_stop_forced(stop)) {ret = NLOPT_FORCED_STOP; break;}
if (nlopt_stop_evals(stop)) {ret = NLOPT_MAXEVAL_REACHED;}
if (nlopt_stop_time(stop)) {ret = NLOPT_MAXTIME_REACHED; break;}
I just added a memcpy from the current estimate to the result:
if (nlopt_stop_forced(stop)) {ret = NLOPT_FORCED_STOP; break;}
if (nlopt_stop_evals(stop)) {
ret = NLOPT_MAXEVAL_REACHED;
memcpy(x, xcur, sizeof(double) * n);
break;
}
if (nlopt_stop_time(stop)) {ret = NLOPT_MAXTIME_REACHED; break;}
I think this can be done for the other stopping criteria but I wanted to
minimize the changes in the code.
Best Regards
Felipe
