Hi,
I'm currently solving a problem where I get this output:

1.5s| 1 | 0 | 1864 | - | 52M | 0 |1580 |8278 |8293 | 6
etc...
Since the column node shows 0 and 1, does this mean SCIP spent 1.5 seconds
on solving 2 LPs ?
Is there any detailed docs about what each column mean, in particular the
"sepa", "confs" and "strbr" (the other ones I have no doubts).
Thanks!
