英文:
What does BESTSOLFOUND mean in SCIP's callback?
问题
I would like to understand the meaning of BESTSOLFOUND in the SCIP_EVENTTYPE_BESTSOLFOUND. I have tried to write a callback to execute this event handler that can be found here. By referring to the related document it mentioned that:
> a new best primal feasible solution was found
Now what I am willing to know is, what does it mean in the context of SCIP's B&B log file? And How can anyone find out when an event occurs?

每当primalbound列中出现新值时，您可以从日志文件中看到新的候选者被发现。
如果您想知道您的事件处理程序是否有效，只需在执行回调中打印一些内容。
英文:
You mean how can you see in the logfile when a new incumbent is found? Whenever there is a new value in the primalbound column.
If you want to know whether your event handler works just print something in the exec callback.
