Dear Ramon,<br>
<br>
this is exactly the same thing we already discussed two weeks ago:
SCIP is not holding any output back, but a root node heuristic is
called and seems to take a huge amount of time. I would guess it is
the subnlp heuristic, but you could check this if you would print
the statistics after solving a problem (or stopping the solving
process). You just need to type "print stat" in the interactive
shell. Then, you will see which plugin consumes how much time.<br>
<br>
During the heuristic call, no output is printed, because it is just
a subroutine and the branch-and-bound process doesn't proceed. If
you press CTRL-C, SCIP interrupts the heuristic and finishes the
current node, so that you get some output before the solving process
is really interrupted.<br>
<br>
Looking at your output below, I can see that you have a primal bound
now, but you didn't copy the line where it is first listed and which
also lists the heuristic responsible for it. Thus, I can only guess
that the heuristic running so long might have found it, so it might
even be worth the long running time. But all of this would be
clearer if you would print the statistics.<br>
<br>
Best,<br>
Gerald<br>

So the issue seems to be that solving a problem in the
SCIP binary holds back the verbose output to the screen
unless I hit CTRL+C. This makes progress info start
streaming on the screen, but then execution stops due to
a user interrupt. </div>
