[SCIP] concurrent solving and BESTSOLFOUND events

[James Cussens]

Hi all,

When I do concurrent solving I find that my event handler for BESTSOLFOUND events ( which records best-so-far primal solutions in a file) does not seem to execute until solving is over. My guess is that this is because the event handler for each scip copy does not know whether primal solutions which are the best that it has found, are the best overall. However, I would like to have the "anytime" behaviour I have with regular solving, where the best incumbent (over all concurrent SCIPs) is output as soon as it is found.

Is this possible?
