双向更改事件类型? [英] Dual bound change event type?

问题描述

我正在尝试编写一个简单的事件处理程序，以便在最佳原始或双重边界发生变化时执行某些操作(请告诉我是否在这里重新发明轮子，并且已经有一种方法可以执行此操作).

I'm trying to code a simple event handler that does certain things whenever the best primal or dual bounds change (please let me know if I'm reinventing the wheel here and there is already a way of doing this).

对于原始边界，我可以捕获SCIP_EVENTTYPE_BESTSOLFOUND事件，但是对于双重边界，我似乎找不到合适的事件类型(在type_event.h中).我看到的所有与绑定相关的事件似乎都是针对可变范围的.

For the primal bound I can catch the SCIP_EVENTTYPE_BESTSOLFOUND event, but for dual bound I can't seem to find an appropiate event type (in type_event.h). All the bound-related events I see seem to be for variable bounds.

我错过了什么吗?还是应该只使用SCIP_EVENTTYPE_NODESOLVED事件之类的东西，然后手动检查全局边界上的更改?

Am I missing something? Or should I just use something like the SCIP_EVENTTYPE_NODESOLVED event and then manually check for changes on the global bound?

谢谢！

推荐答案

是的，没有事件可以捕捉到对偶界限的变化.在SCIP_EVENTTYPE_NODESOLVED事件之后检查对偶听起来是合理的.

Yes, there is no event that you can catch for a change in the dual bound. Checking the dual bound after the SCIP_EVENTTYPE_NODESOLVED event sounds reasonable.
